St Olaves Exhibition Centre Including Forecourt Walls and Railings

St Olave's Exhibition Centre, originally a church, dates back to the 11th century, with the current structure likely built in the mid-15th century. It was restored with some alterations in 1859 by James Harrison and converted into an exhibition centre in the 1980s with minimal changes. The forecourt walls, which once supported a building in front of the Row walk, are of medieval origin. The building is constructed of red sandstone rubble and has a grey slate roof.

The exterior features a simple hall church design with a renewed elliptical-arched west doorway, a boarded double door, and a restored three-light panel-tracery window above the doorway. There is a small gabled stone bellcote. On the south side, there is a rectangular three-light mullioned window and a one-light window with a cusped head further east. The north side has similar windows, but the rectangular window consists of two lights, both with leaded glazing. The east end has a renewed segmental-arched window with three cusped lights, featuring three small modern stained-glass panels.

Inside, the space is very simple and plastered throughout, with noticeably outward-leaning side walls. The forecourt, at the former Row level, includes a sandstone rubble retaining wall and a flight of ten simple stone steps leading up from St Olave's Street to the north. There is a wrought-iron railing along St Olave's Street and the steps, while modern steel railings to the west and south are not included in this listing.
