Once upon a time, there was a wrought iron fence at the entrance to Promenade Hill. It can be seen in this early photograph, taken from Promenade Hill, looking east along Warren Street.
The fence was removed when the entrance to Promenade Hill was reconfigured during Urban Renewal, but, unlike so many other things that were lost forever during that era, the fence survived. It can be found on Green Street, enclosing the front yard at No. 72.
