The Riverside Museum, Edinburgh Castle, Stirling Castle, and Caerlaverock Castle had the International Cycling Union's (UCI) rainbow colours projected against them.

The Glenfinnan Viaduct, Loch Lomond, and the Traquair House were also illuminated to build anticipation for the event.

"We are now into the final stretch of preparations for these milestone UCI Cycling World Championships," said UCI President David Lappartient.

"Illuminating landmarks at key venues in Glasgow and across Scotland has given everyone a true sense of the importance and enormity of this inaugural event.

"Six months will pass by quickly and I cannot wait to see fans and athletes from cycling's many different disciplines join together for these eleven days of excitement, celebration and competition that will crown virtually all of our UCI world champions for 2023."

Thousands of amateur and elite cyclists from more than 120 countries are set to compete across the 13 UCI World Championships in the inaugural edition of the combined event, making it the largest competition in cycling history.

All of the landmarks were chosen as they are located in regions that are venues for the Championships.

"Shining the iconic UCI rainbow jersey colours onto some of the country's most incredible and well-known locations heralds another significant milestone in the run up to the inaugural UCI Cycling World Championships," said chair of the 2023 Cycling World Championships Paul Bush.

"With six months to go until Scotland hosts the biggest cycling event ever staged, the lighting up of landmarks acts as a celebratory beacon ahead of eleven action packed days in August where UCI world champions will be crowned, and audiences wowed by must-see moments.

"Having mega events of this size and scale in our calendar further strengthens Scotland's position as a world-leading events destination and reinforces Scotland’s place as the perfect stage for events."
