Docusign Tower, previously the Wells Fargo Center, is a skyscraper in Seattle, in the U.S. state of Washington.

Originally named First Interstate Center when completed in 1983, the 47-story, 574-foot (175 m) tower is now the ninth-tallest building in the city, and has 24 elevators and 941,000 square feet (87,400 m2) of rentable space.

[8][9] The exterior façade is composed of a six-sided, steel-framed tower that features a combination of tinted continuous double-glazed glass and polished spring rose granite panels.

On the west side, the building has a public hill-climb on two flights of outdoor escalators that were encased in clear tubes until 2006 when they were updated with a simpler, yet more modern glass roof.

[10] The site was previously occupied by the 12-story Olympic National Life building, which was demolished by implosion on the morning of Sunday, February 28, 1982.
