Limehouse DLR from Bank or Tower Gateway, then a 5 minute walk (see below).
15 From Trafalgar Sq.
Walk/ drive/ cycle:
Get onto Commercial Road and travel East from Aldgate/ Whitechapel. Keep going until you pass Limehouse DLR on your right (under the DLR train bridge) and you'll see a modern red brick church also on the right, then you'll see the Town Hall with St Anne's (Hawksmoor) church behind it. If you need to park, there is a pay and display area behind the town hall (drive via Three Colt Street after the church).
