We light the tower at St Edmundsbury Cathedral on special days to bring awareness to certain causes. Last year, we installed new LED lights on the tower, which are more eco-friendly and make changing colours much easier for our team. Below is a list of dates when the Cathedral tower will change colour, and what it means:

• Friday 1 May 2026 (green) – Lyme Disease UK. Find out more here.
