1 From Cornhill, with the post office behind you, turn right to walk along Tavern Street, once filled with pubs but now a pedestrian shopping street. On your right you pass The Walk, a mock-Tudor shopping arcade built in 1933. Turn right along Dial Lane, passing St Lawrence's Church. At the crossroads with Buttermarket, note the Ancient House opposite, with its carved woodwork and decorative pargeting.
2 Keep ahead into Arras Square, passing between St Stephen's Church, now the tourist information centre, and the Buttermarket shopping centre. At the end, turn left along Dogs Head Street and right at the crossroads along Lower Brook Street. Turn left along Rosemary Lane between the red-brick Peninsular House, offices of the P&O shipping company, and Haven House, home to Customs and Excise. Continue around a multi-storey car park to emerge opposite some almshouses. Turn left here and then right along an alleyway beside the ruins of 13th-century Blackfriars Priory, set in the gardens of a block of flats.
3 Cross Lower Orwell Street by a pink timber-framed cottage and turn right along Fore Street. Cross Star Lane via the pedestrian crossing and walk past the Fore Street Baths. At the next junction, fork left past the half-timbered Lord Nelson pub and continue along Fore Street. Cross the road and turn right through Neptune Walk to reach the Wet Dock, the largest in England when it opened in 1842.
4 Turn right to walk beside the marina, passing old maltings and dockside inns. After walking beneath the modern glass extension to Waterfront House, a 19th-century warehouse, you come to the Old Custom House where you can climb to the terrace for the best view of the docks. Continue along the quayside to the end of the dock, then turn right along Foundry Lane and left along College Street past the gateway of a 16th-century college founded by Cardinal Thomas Wolsey.
5 Turn right beside St Peter's Church and continue up St Peter's Street, which soon becomes St Nicholas' Street. Turn left down a pair of steps along a narrow passage leading to the Unitarian meeting house (1699), one of the first nonconformist chapels in England. Walk round to the right of the church to reach the Willis-Corroon building, a remarkable black glass structure designed by Sir Norman (now Lord) Foster in 1975. Cross the road and turn right along Princes Street to return to Cornhill.
