Piccadilly Circus was surrounded by illuminated advertising hoardings on buildings, starting in 1908 with a Perrier sign, but only one building now carries them, the one in the northwestern corner between Shaftesbury Avenue and Glasshouse Street. The site is unnamed (usually referred to as "Monico" after the Café Monico, which used to be on the site); its addresses are 44/48 Regent Street, 1/6 Sherwood Street, 17/22 Denman Street and 1/17 Shaftesbury Avenue, and it has been owned by property investor Land Securities Group since the 1970s.
