Clarence Street Baptist Church.

No ... ::15:

Trinity House taken from outside The Dolphin.

Well you have the right place, that lighthouse stained glass is a giveaway; but you are standing at the wrong end, so where was I standing?

Custom House steps.

Good one . ::15: .. Custom House, the third one Penzance had, built 1812. The earliest one was built down on the old quay. The second was IN Custom House Lane. I have not yet worked out the dates, but I am following early Custom House accounts and advertisements.
