Newton Surmaville, just outside Yeovil, was bought by the Harbin family in the early 1600s, and they immediately set about constructing a very handsome new house. Sometime in the middle of the following century they added this summerhouse on Newton Hill, high above the house, and the story locally is that it was one of a trio of towers in the area, used by their owners to flag the message that it was time to ‘gallop over for a convivial evening’.
