Ludgate Circus is a road junction at the foot of Ludgate Hill, where Fleet Street ends. It is a database landmark in Syndicate.
Statues of King Lud and his sons were added to the gate in the early 1500s; Puritan vandals knocked their heads off in the 17th century, and they were repaired under Mary II.
Ludgate Circus is a database landmark you complete by visiting it. Since it joins Fleet Street to Ludgate Hill, it makes a useful waypoint when travelling from Temple Church and the Fleet Street area toward St. Paul's Cathedral.
