The Tower will be lit up bright for one of York's oldest and most historic sights. So bright, in fact, that it's turned yellow. The 13th century tower is its walls bright yellow in honour of the biggest event to hit York this year.
As the Tour De France's peloton wheels into town, the tower's will be illuminated yellow in honour of the iconic "maillot jaune", or yellow jersey, worn by the leading rider each day of the Tour.
Clifford's Tower will be passed by the Tour De France riders on the second day of the Tour's journey through Yorkshire, with the winner of the previous day's sprint finish on Harrogate's Stray sporting the yellow jersey.
It will continue to be illuminated yellow every day of the one hundred Day Cultural Festival, in the run up to the Grand Depart 2014. It will glow yellow from 6pm-12am daily.
We spoke to shoppers in the town on April 6th, Percy Hanner of Escrick said "This will be a lovely sight to see on an evening and will remind everyone what a special occasion it is for York and Yorkshire with the Tour De France being hosted in our region. I hope people appreciate it."
English Heritage's Julie Spowart, has stated that "York is very proud to be showing support and celebration of Yorkshire's Grand Depart by literally turning Clifford's Tower yellow at night as part of the 100 day Cultural Festival in Yorkshire. As an iconic landmark in the city, it's great to see this beacon of yellow shining on the route that the cyclists will follow on their route."
