Milecastle 39 (also known as Castle Nick) was cleared in 1854, and excavated between 1908 and 1911. It was re-excavated between 1982 and 1987.
In the south-east corner was a stone oven and the south-west corner a rectangular building with a sunken floor associated with Roman finds.
The milecastle appears to have been occupied until the late 4th century. In the 18th century, a possible milking house was built in the west corner.
This is probably the most photographed spot in the whole of Northumberland National Park. Here, a sycamore tree grows in a dramatic dip with Hadrian’s Wall rising up either side. The 1991 film ‘Robin Hood: Prince of Thieves’, starring Kevin Costner, was filmed here. The tree has been known as The Robin Hood Tree ever since.
