The Great Western Main Line was considered as a potential UNESCO World Heritage Site in 2006 but rejected in 2011.[134] The proposal comprised seven sites: Temple Meads (including Brunel's GWR offices, boardroom, train shed, the B&ER offices, and the bridge over the River Avon); Bath (including the route from Twerton Tunnel to Sydney Gardens); Middlehill and Box Tunnels; the Swindon area including Swindon railway works and village; Maidenhead Railway Bridge; Wharncliffe Viaduct; and Paddington station.[135]
