Glasgow's Hydro stadium turned gold in honour of the record medal haul achieved by Team Scotland in the Commonwealth Games.
On day six Scotland's silver and bronze medal haul took the host nation's total to 37 medals. The haul of 33 at Edinburgh 1986 had been Scotland's previous Games best.
TSSE Hydro had tweeted the news earlier in the day: "In honour of the record medal haul from Team Scotland at Glasgow 2014, the Hydro building will turn gold at 9:30pm tonight."
The Hydro changed to gold over an hour and a half as the sun set over the city.
