State Capitol Building
If you are lucky enough to be in Salem on a sunny day you should go to the Capitol building and take the tour to the top of the building to see the Gold Man The Golden Pioneer. Observation Deck tours are available to the public, on the half hour, Memorial Day through Labor Day. There are parks located all around, complete with gardens and large fountains. The fountain directly in front is a haven for kids to play and cool down in the summer time.
