Vincent Lugo Park, the largest park in the City of San Gabriel, sits tucked into a postwar tract-home neighborhood bordering the Alhambra Wash. Past the metal-and-plastic play equipment, a winding path through mature palms and tropical foliage guides visitors into an otherworldly sculptural playscape: La Laguna de San Gabriel. Designed and hand-sculpted by master concrete artist Benjamin Dominguez, La Laguna is a 19,000-square-foot amoeboid-shaped sandpit “lagoon” inhabited by fourteen towering mythical sea sculptures. Opened to the public in 1965, La Laguna is Dominguez’s nautical fantasy world brought to life. Yet the artist’s legacy remains obscured in the canon of midcentury experimental playscapes, strikingly disproportionate to the enduring affection that generations of families hold for his playground, known locally as “Monster Park.”(1)

Unlike the standardized playgrounds that dominate American urban space—interchangeable from one city to the next and divorced from the land they occupy(2)—La Laguna de San Gabriel is an immersive work of public art conceived in direct connection to the physical and cultural landscape. It reflects the essence of a regional Pacific modernism, shaped less by European precedents than by cultural exchanges, migrations, and the fusion aesthetics of the Pacific Rim. While dominant narratives of Los Angeles modernism celebrate the engineering innovation of the city’s freeway system or private single-family landmarks like the Case Study Houses, public parks and playgrounds rarely enter the picture. Centering La Laguna and Benjamin Dominguez reorients Los Angeles modernism from private enclaves to the public realm and highlights the vital role of Mexican art and transpacific aesthetics in shaping the region’s public space.

Metabolizing Freeway Urbanism

Two years after La Laguna opened to the public, a 1967 Los Angeles Times headline read, “Born in a Dump 17 years ago, Park Grows Like Living Thing,” reflecting nearly two decades of citywide efforts to convert a municipal landfill into a park. La Laguna was the final play area added to the park, replacing earlier plans for tennis courts.(3) The twelve acres that became Vincent Lugo Park once formed part of an alluvial floodplain along the Alhambra Wash. In the early twentieth century, the landscape belonged to the Citrus Belt economy, where white Americans owned the land and controlled profits, while Mexican and Asian immigrant laborers harvested the crops.(4) In the 1930s, the US Army Corps of Engineers encased the wash in a concrete flood-control channel. On the federal government’s 1939 redlining map—drawn by the Home Owners’ Loan Corporation to grade neighborhood mortgage risk by race and class—the site of the future playground fell directly on the border of a redlined zone categorized as a “low grade Mexican section”.(5)

Postwar Los Angeles was engineered around private car ownership and sprawling suburbia. This vision was cemented by a comprehensive freeway plan based on the redlining maps, together with land appraisals and eminent domain to seize low-cost property and route highways through working-class neighborhoods, displacing and fracturing communities along lines of race and class.(6) The San Gabriel Valley felt the full force of this expansion as historic farmworker barrios were razed to accommodate suburban growth driven by the extension of the San Bernardino freeway, while housing expansion built directly upon these patterns of disinvestment, pushing longstanding Mexican American and Asian American families deeper into redlined areas.(7) As suburbanization accelerated, the natural ravine was converted into a city dump, absorbing the concrete rubble from freeway construction.

The city of San Gabriel purchased the land in 1951, as its population swelled by nearly two-thirds in a single decade.(8) Park supervisor Vincent Lugo—a descendant of one of California’s oldest land-grant families—and Parks and Recreation Director Frank H. Carpenter spent over a decade filling the ravine, remediating the wasteland, and building the parkland through piecemeal planning. Such park-planning initiatives were exceedingly rare in Los Angeles, which has struggled with a systemic park deficit since the Great Depression, particularly in working-class and redlined neighborhoods.(9) For the park’s final play area, Carpenter sought a defining attraction that would be unrivaled by neighboring cities.(10) At the time, many American cities were developing novelty and storybook playgrounds, whose figurative play sculptures brought fantasy, storytelling, and immersive aesthetics to urban spaces that increasingly understimulated or restricted children’s imaginations.

Carpenter first encountered Benjamin Dominguez’s concrete play sculptures at Atlantis Park, another nautically themed fantasy park in Garden Grove. Recognizing the artist’s extraordinary craftsmanship, he saw Dominguez as the visionary who could give San Gabriel’s new park its defining feature. Carpenter executed an unprecedented planning strategy, handing full creative autonomy to a commissioned artist by allocating a single line item in the city budget for the entire playground’s footprint.(11) Even in this era of playground experimentation, city bureaucracies typically resisted artist-designed projects without much oversight; Isamu Noguchi’s repeatedly rejected proposals in New York City exemplify that friction. Dominguez’s earlier California commissions reflected this frustration for the artist as well. His sculptures at Legg Lake in Whittier Narrows, for example, were commissioned per piece, which kept him from realizing a full playscape and undermined his intention to create works in dialogue with one another and their surroundings. La Laguna grew instead from a meaningful collaboration between city officials and the artist, allowing the artwork to exist in its intended composition and landscape. Carpenter credited its success to the city’s willingness “to stretch the imagination a little and create an unusual atmosphere not found in most parks.”(12)

Viewed through this long arc of land transformation and planning history, La Laguna holds a radical place in the region’s urbanization, metabolizing concrete—the material of discriminatory spatial ordering—into a public commons that centers children and intergenerational community in civic life.

Benjamin Dominguez and Concrete Whimsy

Benjamin Dominguez was born in 1894 in Guanajuato, Mexico. He studied at the prestigious Academia de Artes Plásticas (San Carlos) in Mexico City, where he mastered trabajo rústico (faux bois), a Mexican folk-art evolution of European ornamental masonry that textures wet cement over steel rebar to hyper-realistically mimic wood, stone, and organic forms, emphasizing natural imperfections. Dominguez immigrated to the United States with his family in the 1950s, bringing a craftsmanship that was extremely rare in California. His passion for playground design grew from his life as a father of thirteen children. His intimate understanding of child psychology guided every detail of his sculptures, from their smooth organic contours to the dual access points (both gentle and challenging) that allowed children at different developmental stages to navigate beneficial risk.(13)

La Laguna is the final project Dominguez completed by hand at age seventy. His careful consideration of landscaping and composition seems to reference the relational staging of late Renaissance sculpture gardens. His worldbuilding extends into the details of La Laguna’s organically shaped sandpit and surrounding foliage, where an “island berm” of palms, dracaenas, and pines extends the aquatic environment while enclosing the playscape within a lush wall of plant life. This landscaping echoes the Polynesian-inflected “exotica” trend popularized by the surrounding apartment complexes and commercial plazas of the era.(14)

At one end of the lagoon sits a child-sized sinking ship, The Red Pirate, surrounded by three seals perched on sculpted rocky mounds, with a treasure chest lying partially submerged nearby. The ship and the chest explicitly display Dominguez’s mastery of trabajo rústico, where red-pigmented concrete is hand-tooled to reproduce weathered wood grain and the splintered mast planks. The ship’s upward-curving bow subtly morphs into the neck, eye, and beak of a mythical seabird. The figurehead is easy to miss, creating another playful point of discovery and animating the vessel into a living creature among the other sea monsters. On the rocks beside the chest, Dominguez carved the date “1765,” exactly two hundred years before the park’s opening. It is a subtle historical clue to the decade preceding Spanish Franciscan missionization in the San Gabriel Valley, an era that initiated the violent dispossession of Indigenous Tongva people and permanently reformed the land through colonial conquest. Perhaps this clue sets the stage for imagining counter-histories for land and people.

Two towering lookouts, the Lighthouse and Lookout Mountain, anchor the lagoon’s perimeter, each wrapped in giant sea serpents whose concrete bodies hollow into slides. From the top of Lookout Mountain, La Laguna's highest vantage point, the surrounding landscape reveals two opposing stories of concrete placemaking. Looking south, beyond the park boundary lies the channelized Alhambra Wash, a conduit that mirrors the nearby freeways and embodies a legacy of technocratic engineering, community displacement and containment. Yet looking inward to La Laguna, the same material forms a warm, whimsical playscape, becoming a medium for spatial belonging.

Despite Dominguez’s extraordinary design achievements, historian Eloy Zarate found that early records omitted his name, reducing him to the dehumanizing moniker “the Mexican.”(15) Recovering Dominguez’s significance is essential to revisiting the canon of midcentury experimental playground design. While figures like Isamu Noguchi, Louis Kahn, and Aldo van Eyck are rightly celebrated for their contributions, Dominguez brought an unrivaled synthesis of Mexican folk craft, Pacific aesthetic sensibility, and fantasy worldbuilding to the fabric of public space.

Preservation and the Politics of Play

The golden age of artist-designed playgrounds ended suddenly in the late 1970s and 1980s. Escalating insurance costs and growing liability pressures threatened local governments with personal injury lawsuits. Playgrounds across the United States were deemed safety hazards, and cities swept them away in favor of uniform, modular “post-and-platform” systems. These pressures reached La Laguna de San Gabriel in 2006, when the city slated the playground for demolition as part of a broader park modernization scheme. In response, historians Senya Lubisich and Eloy Zarate partnered with community members to form Friends of La Laguna (FoLL), mobilizing neighbors and collecting more than 2,500 signatures. The overwhelming public outcry compelled the city council to halt demolition and instead partner with FoLL on an extensive, multi-year restoration. FoLL’s advocacy secured La Laguna’s designation on the California Register of Historical Resources in 2009 and the National Register of Historic Places in 2017 under the theme “Latinos in Twentieth Century California.” This national recognition, made possible by Zarate and Lubisich, formally reclaims Dominguez’s place within the canon of modern public art and architecture.

The enduring impact of La Laguna de San Gabriel for the surrounding community illustrates the cyclical nature of playgrounds as a vital democratic commons. As generations of children who played on Dominguez’s sea creatures return as parents and grandparents, the playscape functions as an intergenerational anchor where memory, identity, and imaginative freedom continuously re-emerge. For the San Gabriel Valley—a historically and culturally underrepresented region of Greater Los Angeles—La Laguna exemplifies the region’s architectural significance while celebrating transpacific aesthetics, civic resilience, and the whimsical worlds that become possible when people hold power over public space.
