Site of Ludgate demolished 1760.
The Corporation of the City of London
Site: Ludgate + King Cadwaladr (2 memorials)
EC4, Ludgate Hill, St. Martin-Within-Ludgate
This church bears a blue plaque, to the far left, and two pink boards on which the text is becoming difficult to read. That to the right is about the various guilds etc. that use the church but the one on the left carries some interesting information which we can consider a memorial to King Cadwaladr.
Immediately opposite the church is Pilgrim Street. A few yards down here, at a bend in the road you will find a large stone protecting the corner building from damage from vehicles negotiating the tight corner. Londonist reports a suggestion that this is a relict of the old Ludgate, which was conveniently nearby.
