The present building was erected in 1902 but a plaque inside says it stands on the site of an earlier hall built in 1337 and it is thought that another preceded that.
The mayor and burgesses gained its use from the Guild of St Mary in the reign of Henry VIII. A Judge of Assize sat there in the last century, Courts of Quarter Sessions until after the last war and until more recent years it was a Magistrates Court.
The Guildhall is situated on the Market Place in Thetford and is an ideal location for meetings, small scale theatre; choral or spoken word events, accommodating between 40-120 persons depending on the room hired.
The Guildhall offers three rooms for hire, these being The Large Court, Small Court and Council Chamber.
