The Beehive well
Beehive shaped brick structures covering wells can be found throughout the world, often to be seen with wrought iron gates. While also meant for the use of the local community, they were easily recognised by travellers as places where they could get fresh water, the gates no doubt offering assurance that no wild animal had been into them (or even lurked within them still). They are often dated to the 18th century.
The beehive well in Welbourn can be found built into the wall of The Nookin by continuing along the metalled track a little beyond where the waymark shows the exit from the village onto the Public Footpath.
