Heritage Plaza

A Slice of History in Downtown Hayward

In 1864, Don Guillermo Castro - Hayward's first landowner and rancher - dedicated an entire city block to local residents as a permanent public plaza. That generous gesture is the foundation of Heritage Plaza, a spacious public area that spans the same footprint as San Francisco's Union Square.

The land has seen quite a few chapters since then. It once held a Carnegie library, then another library building, before eventually becoming the green oasis it is today. It's a place where Hayward's history breathes alongside modern community needs.

What You'll Find There

Heritage Plaza is Hayward's go-to spot for community happenings. The layout includes a sprawling 25,000-square-foot central event lawn paired with an 11,000-square-foot paved plaza along C Street.

Together, these spaces can accommodate nearly 4,000 people during events - pretty impressive for a downtown plaza! Tree lovers will be in for a treat.

The plaza contains over forty species of rare and mature trees, with some dating back more than a century. During renovation, these trees were carefully preserved.

Take a leisurely stroll along the "arboretum walk" paths flanking the central lawn, where informative placards introduce you to each species. The landscaping combines hardscape elements with natural beauty, appealing to both casual wanderers and plant enthusiasts.

Cultural Touchpoints

The plaza honors Hayward's diverse cultural history through interpretive signs and art installations. Three key art pieces are in the works to pay tribute to the Muwekma Ohlone Tribe, the Japanese-American community, and former Russell City residents.

These installations aren't just decorative - they tell important stories about the area's indigenous peoples, the internment of Japanese Americans during World War II, and the displacement of Russell City residents in the 1960s.

Smart Environmental Design

An interesting feature you might not notice at first glance is the plaza's rainwater catchment system. The entire space doubles as a rainwater collector with underground storage and filtration.

This smart design captures and repurposes up to 200,000 gallons of rainwater annually, which gets treated and used for irrigation throughout the plaza and gray water needs in the adjacent library building. It's sustainability hiding in plain sight.

Your Visit Experience

Heritage Plaza offers a welcome patch of green in downtown Hayward where you can simply relax and unwind. The open lawn is ideal for a picnic - you can bring a blanket and some snacks to enjoy an outdoor meal.

The plaza sits surrounded by city streets, making it easy to find but definitely urban in character. While seating options are somewhat limited within the plaza itself, the generous green space more than makes up for it.

Note that there aren't public restrooms in the plaza, but don't worry - the Hayward Public Library stands right across the street with facilities available during its operating hours.
