Hay's Galleria is a mixed use building in the London Borough of Southwark situated on the south bank of The River Thames including offices, restaurants, shops and flats. Originally a warehouse and associated wharf (Hay's Wharf) for the port of London, it was redeveloped in the 1980s. It is a Grade II listed structure.
Office tenants have included the UK social work regulator, the General Social Care Council, and the Social Care Institute for Excellence. The pub at the riverside entrance, 'The Horniman at Hay's' is named to commemorate one of the main tea producing companies associated with the trade here.
Due to its location on the southern Thames Path, its panoramic views over the City of London from the riverside, and the location between London City Hall and Southwark Cathedral, Hay's Galleria is visited by many tourists and local workers. For twenty years it housed a year-round market The Hays Galleria Market which operated seven days a week. It had a resident artist and for more than 2 decades it was home to several permanent independent traders,long-term tenants of St Martins's Property Corporation selling souvenirs, touristic apparel and jewellery from traditional barrows positioned in fixed locations in the Galleria, On 8 October 2010 on the orders of CBRE the Managing Agents the barrows were removed.
