The Green Dragon is one of the oldest pubs in the country with the original building dating back to the 14C, and has been the home for a pub since the 16C. Much of the exterior is Tudor and half-timbered with a dormer window. The interior retains many historic features such as beams and mantelpieces, and consists of a bar, snug, bar/restaurant area and an upstairs bar and function room.

The Great Fire of Wymondham, which broke out in 1615, was a major event in the town's history. About three hundred properties were destroyed in the fire, however the Green Dragon survived and scorch marks from the fire can be seen on the building to this day.

The pub has a large beer garden with a large grassed area and a gravelled area, all with bench and table seating, some of which is under cover.
