English: St. Mary's Minster : West End The twin Norman towers at the west end of Southwell's magnificent St. Mary's Minster. The unusual "Rhenish caps" (or "pepperpot") spires atop each of the towers, the only examples in the country, were removed as unsafe in 1805, but were replaced at the end of that century. The church was built in the first half of the C12th during the reigns of Henry I & Stephen. Work started c.1108 at the east end proceeded westwards, finishing with these towers in about 1150. The minster was elevated to the status of cathedral in 1884 when the new Diocese of Southwell was formed. In 2005 the Diocese changed its name to the Diocese of Southwell and Nottingham.
