More than 40 businesses will be illuminated when Light Up Cheltenham returns for three weeks from February 2.
Among the prominent buildings to be lit is the historic dome that now makes up part of The Ivy Montpellier Brasserie.
Cheltenham Business Improvement District (BID) is organising the three-week celebration, which will also feature a giant observation wheel, standing more than 35-metres high in Imperial Gardens.
Historic buildings on The Promenade and Clarence Street will also be taking part in Light Up Cheltenham for the first time.
Luc Morel, General Manager at The Ivy Montpellier Brasserie said: “We’re looking forward to being involved in this year’s Light Up Cheltenham alongside many other local businesses and iconic buildings in the area.
“It’s an exciting local initiative and we can’t wait to see our beautiful building changing colour over the next few weeks.”
There will be a range of colours displayed and all the buildings will turn red for Valentine’s Day. As well as many buildings having floodlights for the first time, other permanently-lit businesses will change their colour schemes to be part of Light Up Cheltenham.
Spectacular street theatre drumming group Spark!, who were a massive hit at the first Light Up Cheltenham last year, will return to launch the event from 5pm on Saturday February 2. Further entertainment will be provided by the Photon Juggling LED Glow Show on Saturday February 16 at the start of the half-term holiday.
BID Director Kevan Blackadder said: “The response from businesses of all kinds has been fantastic. The community spirit has shone through, with so many people wanting to be involved.
