@Smiffy - a very strong connection, I'm researching the Magnus family and the Synagogue for a small article. I've "heard tell" that it was known as "Magnus' Wharf" within living memory, but I need some sort of reference to confirm it. @Shoot99 - the Synagogue still pays 5p per year for a yard-wide strip of land to the west of the site. It's still visible if you look carefully, but the gate is back now after the vandalism of last year and bolted shut.
