Heritage walk and sea front park?

I have seen on old walking tour maps of Falmouth that the landscaped area to the right (as you exit) of the parking lot is included in the heritage walk. The first time we went to Falmouth the access gate was locked and I thought perhaps the area was not finished but it was still locked when we visited a couple of weeks ago. Has anyone ever been in, or know what the area is for, or is it private? It has a walk way and seats.
