Morpeth Town Hall is closed for functions for three weeks due to extensive toilet works.
Work began on Monday to reconfigure the pipework for the first floor toilets following problems with blockages.
The project, organised by Northumberland County Council, means taking down the ceiling of the Corn Exchange to access the pipes.
Northumberland Registration Services are continuing as normal and arrangements have been made to accommodate three weddings when the workers are off-site.
However, no other functions can take place.
Morpeth Town Council Clerk Gillian Turner said: “We are still able to have council meetings in the Council Chamber and the registrars are still taking bookings for birth, marriage and death registration, but we are not having any functions in the Town Hall as there are no toilets to use.
“They have to take the ceiling down in the Corn Exchange to access the toilet pipework and re-fit the pipes and pumps so the downfall is better. It is quite a big job, with scaffolding and a small space to work in.
“This had to be done because when there were lots of people using the Town Hall the toilets would block up and there have been a couple of occasions when they have leaked through the ceiling.
“The public should see no difference in the appearance of the building when the work is done.”
