The Rochester Bridge Chapel is one of the few surviving chapels of its kind in the country.
It was built at the end of Rochester Bridge in 1393 and had three priests who would bless travellers on their journeys.
People crossing the bridge would stop there and pray for safe passage.
It stopped being used as a chapel in 1548 and was then leased out for various purposes including as storage, a house, an alehouse and a sweetshop.
It had become a ruin by the 1800s and was restored in 1879 when the Victorian Bridge Chamber was built beside it, which has been used by the Rochester Bridge Trust for many of its meetings.
The buildings and exhibition will then be open from 11am until 4pm. In 2023 the exhibition will re-open on Wednesday, 1 February, running until Thursday, 30 March. No booking is required.
