 The castle ruins are set at the top of a hill overlooking the Thames Estuary, and the Canary Wharf development nearly 30 miles to the west can be seen when visibility is adequate.Another building of note is the Church of St James the Less which was believed to be Norman but is now known to be Saxon because of its general dimensions, window alignments, Saxon Romanesque arches, pagan Saxon "puddingstone" inclusions and the pagan Saxon "fairy wheel" motif carved into the wall by the north door.The church remains picturesque and its neighbouring street layout resembles St Clement Danes in that it stands in the middle of a bustling high street.
