The full guide

Denny Park is Seattle's oldest park, a full city block at 100 Dexter Ave N in South Lake Union. Pioneer David Denny gave the land to the city in 1861 as a cemetery, and in 1883 it became Seattle's first park. Today the block still holds traces of that past, from a historic bust to a school cupola.

The park sits in the Cascade district of South Lake Union, between the office towers and apartment blocks that now surround it. It is a good stop for anyone curious about how much the ground beneath Seattle has changed.

Denny Park History: From Cemetery to Seattle's First Park

Denny Park began as Seattle Cemetery, on land David Denny donated in 1861. Twenty two years later, in 1883, the graves were moved and the city converted the grounds into its first public park.

By 1904 the streets around the park had filled with homes, and the city upgraded the grounds to match. Formal planting beds went in, along with swings, play equipment, a sand lot and a play field. Children were among the park's most regular visitors from the start, helped by the Denny School, an elementary school that stood just southeast of the block from 1884 to 1928.

How the Denny Regrades Reshaped the Block

Denny Park once sat on the north slope of Denny Hill. Between 1900 and 1931, Seattle flattened much of its central hills in a series of regrading projects, and this park was caught in the middle.

Regrade No. 1: a park left on a hilltop

Around 1910, the first Denny Regrade cut the land south and west of the park down by roughly 60 feet (18 m). Surviving Seattle pioneers pushed for the park to be left alone, and they won. The catch was that the park now stood above its surroundings, and cars could no longer reach it from the downtown side.

Regrade No. 2: flattened and replanted

Around 1930, the second regrade brought the park down to level ground, and it was replanted in a formal style. The old Denny School was demolished in the same project. Its cupola was saved and set in the park as a historical marker.

Landmarks Within Denny Park

Denny Park's small footprint holds several pieces of city history. Look for these as you walk the block.

  • The Mark A. Matthews bust: installed in 1941 to honor the minister and activist.
  • The Denny School cupola: placed here around 1930 as a marker of the school lost to the regrade.
  • The Parks and Recreation building: built in 1948 to house the growing city department, despite objections from the Denny family. For several years its lower level was home to the Washington Society for Crippled Children, and by 1964 Parks Department staff filled the whole building.
  • The play area and lighting: the first phase of a park renovation, which opened on May 2, 2009.

A Park With Neighborhood Advocates

Denny Park has a group of supporters, Friends of Denny Park, who advocate to city government for safety in the park. The coalition works with city departments to revitalize the grounds for the people who use them and for the nearby South Lake Union and Denny Triangle neighborhoods.

The park has had hard stretches too. In 2020 a large homeless encampment grew on the block, and some residents stayed away out of safety concerns. After a cleanup by the volunteer group We Heart Seattle, the city cleared the remaining camp. For current conditions, hours and park rules, check with Seattle Parks and Recreation before you go.
