Hay Butter Market was erected by a local entrepeneur by the name of William Enoch in 1830. It replaced a very old open market in order to provide a covered market area for the use of local traders and farmers on market days which have always been a Thursday. It is situated right in the centre of town by Hay Castle Square.
The building had been walled up since just after the second World War but was opened up and restored by Hay Warren Trustees in 1985.
The Trustees won a "Prince of Wales Award" for this restoration. It is now used again every Thursday and also by other traders and charity organisations on most Saturdays and holiday weekends.
The building attracts many locals and visitors as it is right in the middle of town in the main (Castle) square. It can be hired at favourable rates, especially if you are a local or national charity.
