supported at its ends by concrete and steel columns. Both the walls and roof are clad with metal corrugated custom orb sheeting. Lining the perimeter of the concrete deck are a series of shade structures. Area 4 East of the dairy pavilions and the railway line, in the area to the northeast of the Main Arena and bound by O'Connell Terrace, Brookes Street and Gregory Terrace, are the main livestock facilities. The principal elements of cultural heritage significance in this area include: 17. Beef Cattle Pavilion (1950) This is a large, rectangular, single-storey brick pavilion with sub-floor and a saw-tooth roof, located to the north of the Machinery Hill stands, with the rear wall erected along O'Connell Terrace. The front elevation, which faces south, has a centrally-positioned entrance with steel roller door on the upper level, accessed via a double stair. To either side of the front entrance are banks of hopper windows on both levels. The side and rear walls have less fenestration and there is a large rear entrance (another steel roller door) to O'Connell Terrace. 18. Stock Pavilion The Stock Pavilion is on the eastern side of the Beef Cattle Pavilion. It has a series of skillion roofs set in a saw tooth pattern as the building follows the slope. They are clad with corrugated iron. The walls are weatherboard and the upper section is timber lattice. Doors on eastern side are sheet metal double doors, but two central doors now have steel roller doors. The area along the wall of the building from the eastern side has a narrow corridor flanked by "lockers" (small rooms with racks). The corridor wall is vertical beaded board, the floors are patched concrete and the outer wall is concrete. The building appears to have been built in two stages, the eastern section has timber trusses and timber frames to the tethering area and looks older than the western end which has steel trusses and partition frames. The tethering area consists of low walls running parallel along the length of the building, equipped with steel rings for tethering animals and hay racks for them above. When the place is occupied, rails are erected to separate each bay and sawdust and sand bedding is put down. Around most of the perimeter of the building are very basic sleeping quarters for people showing their animals at Ekka. There are a few animal pens
