Pioneer Square pergola, Cast iron pergola in Pioneer Square, Seattle, United States.

Pioneer Square pergola is a Victorian-style triangular shelter of cast iron and glass at 1st Avenue and Yesler Way, designed by local architect Julian F. Everett. It measures 60 feet long and 16 feet high, carried on twelve Corinthian columns with sixteen arches and a glass roof. Built in 1909 as a comfort station, it was rebuilt in 2002 using iron from the original structure.

Built in 1909 to shelter passengers waiting for cable cars on the James Street and Yesler Way lines, the pergola was designed by local architect Julian F. Everett and cost $24,000. It was restored in 1972 with a $100,000 donation from UPS founder James E. Casey, destroyed by a semi-truck in 2001, and rebuilt for $3.4 million in 2002.

The pergola's name comes from its function as a shelter, and its design by Julian F. Everett reflects Victorian tastes. Its 1909 opening included an underground restroom with terrazzo floors and white Alaskan marble stalls, controversial at the time. Today it remains a gathering point in Pioneer Square, where visitors can see the twelve Corinthian columns and sixteen arches rebuilt after the 2001 truck collision.

The pergola sits at the corner of 1st Avenue and Yesler Way and is easy to reach on foot. The location sits in a compact historic neighborhood with several other landmarks nearby.

Beneath the pergola sat a public restroom with Alaskan marble and brass fixtures, a surprisingly refined facility for a utilitarian structure. This underground space revealed how early 20th-century designers brought quality finishes even to everyday community amenities.
