In that first photo I take it the white outline on the ground is the footprint of where the actual for used to be. Is any of the earthworks still visible there?
Cheers!

The Fort Pitt Museum is located in Point State Park.
Point State Park, located at the confluence of three rivers, is at the tip of Pittsburgh’s “Golden Triangle.” It commemorates and preserves the strategic and historic heritage of the area during the French and Indian War (1754 - 1763).
Once a busy industrial area, the area had deteriorated into a commercial slum by the 1940s. The development of a state park was authorized in 1945 and the first parcel of the 36-acre property was purchased in 1946. The park was completed and dedicated in 1974. It is now one of the nation’s outstanding historical parks and tourist attractions and has been designated as a National Historic Landmark.
If The white outline on the ground (the circle)is what you are talking about then that is actually a fountain which shoots water 100 feet high into the air......
The fountain is operated daily from 7 a.m. to 11 p.m. weather permitting, during the spring, summer and fall seasons.
However it has been closed for 2010 and 2011. They are cleaning and updating all the mechanic equipment.
When the fountain is in operation, there are over 800,000 gallons of water in the system. Three 250 hp pumps operate the main column of the fountain which reaches to 100 feet high. Three 75 hp pumps operate the three fan design water features known as peacock tails which symbolize the three rivers. Lighting around the fountain enhances the grandeur of this best known feature of the park.
The circular basin of the fountain is 200 feet in diameter and the water within the fountain is re-circulated. Water to replace the amount lost during fountain operations is obtained from a 54-foot deep well that penetrates sands and gravels under the park.
Here it is in operation.

I added the water information for Blackthorn as it wasn't working when he was here.
