Somerton's Market Cross or Butter Cross is its most famous building.

There are references to an earlier cross on the site, but this one was built in 1673 by the Hext family, as intended by Sir Edward Hext in a letter he wrote to the Vicar of Kingsdon in 1596: 

"but also [I] will (at mine own charge) build a fair cross, that the people may sit dry to sell their butter, cheese, apples, oatmeal, cabbage, roots and other such things as are sold at a cross (if the bailiffs of the market will appoint a fit place for it, which I have no doubt they will do for their own good.) and so upon the whole matter I shall be at the charge of CCCli [£300] for the good of the country and all theirs, so long as it shall please our merciful God to continue it."

It belonged to the Earls of Ilchester until they found they could not afford to repair it during World War I, when it was given to the town.  It is still used as a flower stall during Thursday markets and for charity sales of cakes and bric-a-brac at weekends.
