The water tower was built in 1906, stands at 75.5 feet tall, and has an observation deck on top that gives excellent views of Seattle.
Two Olmsted designed water features can be found near the reservoir. There is also a musical amphitheater, as well as a handful of sculptures to be found within the park's borders. The reservoir was built in 1901.
The conservatory was built in 1912 as part of the Olmsted plan. In 1922, greenhouses were added to the back to act as support for the displays. One noted feature is its extensive Orchid collection, which was donated by Anna H. Clise in 1921. In 1980, the need for renovation and repair led to the creation of a specialized funding program for the conservatory, which is why it is in such good condition today, as well as why we are asked for $3 at the door. It is pretty amazing to visit though, especially when the plants are in bloom.
