St. Peter and St. Paul's Church, Wissembourg: St. Peter and St. Paul's Church (French: "Église Saints-Pierre-et-Paul" ) of Wissembourg is frequently, but incorrectly, referred to as the second largest Gothic church of Alsace after Strasbourg Cathedral.  However, the building, with its interior ground surface area of 1320 m2 (60 x ) most probably is the second largest Gothic church in Bas-Rhin which is one of the two departments of the Alsace region.  The former abbey church ("abbatiale") of Wissembourg's famous Benedictine abbey now serves as the main Roman Catholic parish church of the town.

Pottery Lane: Pottery Lane is a street in Notting Hill, west London.  Today it forms part of one of London's most fashionable and expensive neighbourhoods, but in the mid-19th century it lay at the heart of a wretched and notorious slum known as the "Potteries and the Piggeries".  The slum came to the attention of Londoners with the building of the Hippodrome in 1837 by entrepreneur John Whyte.  Unfortunately for Whyte a public right of way existed over his land and "dirty and dissolute vagabonds" from the nearby slum invaded his race-course, adding to his financial difficulties and, in part, leading to the closure of his venture in 1842.  Pottery Lane gradually improved in the late 20th century along with the rest of the Notting Hill area, today the houses fetch multi-million pound prices.  Just one of the original brick kilns still survives; it is located in Walmer road, just north of Pottery Lane, and bears a commemorative plaque placed there by the Royal Borough of Kensington and Chelsea.

Edelin (abbot): Edelin (? –1293) ruled over the Alsatian abbey of Weissenburg as its abbot from the year 1262 until his death on 15 October 1293.
