Lollard Prison, Lambeth Palace
Lambeth Palace is the official London residence of the Archbishop of Canterbury. It is located in Lambeth, on the south bank of the River Thames a short distance upstream of the Palace of Westminster on the opposite shore. It was acquired by the archbishopric around 1200. The so-called Lollard's Tower, which retains evidence of its use as a prison in the 17th century, dates from 1440.
