Built in 1906 as part of the Olmsted Brothers' park project, the Volunteer Park Water Tower offers one of the finest views of the city. Climb the 106 steps for a full 360-degree vista from the north end of Capitol Hill, at an elevation of 570 feet. On a clear day, peering over tall trees and the rooftops of nearby mansions, you'll spy Lake Washington, Mount Baker, and Mount Rainier. The circular tower's interior is ringed with the Olmsted brothers' designs for Seattle's city park system, detailed with hand-rendered sketches, beautifully written proposals, and ambitious plans far ahead of their time. —Adriana Grant1247 15th Ave. E.
