Paternoster Square is a former historic square, renamed from Newgate Market c. 1872, and now a post-war urban redevelopment, owned by the Mitsubishi Estate, next to St Paul's Cathedral in the City of London. The area, previously named Paternoster Row, after the street of the same name, once centre of the London publishing trade, was devastated by aerial bombardment in The Blitz during World War II. It is now the location of the London Stock Exchange which relocated there from Threadneedle Street in 2004. It is also the location of investment banks such as Goldman Sachs, Merrill and Nomura Securities, and of fund manager Fidelity Investments. The square itself, i.e. the plaza, is privately owned public space. In 2004, Christopher Wren's 1669 Temple Bar Gate was re-erected here as an entrance way to the plaza.

Paternoster Vents, sometimes referred to as simply Vents and also known as Angel's Wings, is an outdoor 2002 stainless steel sculpture by Thomas Heatherwick, installed Paternoster Lane on the west side of the Paternoster Square development in London, United Kingdom, close to the junction of Warwick Lane and Ave Maria Lane with Amen Corner. The sculpture provides ventilation for an underground electrical substation.
