Tocketts Ironstone Mine Shafts

Two mine shafts are easily visible from the footpath though the woods.

The first is a pumping shaft surrounded by a fence, it is 70ft deep and full of water and debris, a bricked up passage can be seen which was presumably to let water flow out into the beck after pumping.

The second is an air shaft with a large chimney, to aid the airflow in the sheltered valley.

Upleatham Church (almost) the smallest in Britain.

Upleatham Church 2
Upleatham Church 5
St Andrews at Upleatham, for years I was told this is the smallest church in Britain, but unfortunately that honour goes to Bremilham Church in Wiltshire at 4m by 3.6m. Upleatham is about 6m by 4m
It is actually the remains of a much larger church as can be seen in this detailed report from the 1970s
Remains of the Lowther Vault exist towards the south-east

Marske Mill, Saltburn

There is evidence that the mill existed in 1649 and it was used for milling until the 1920s. The site contined as a farm but was eventually demolished in 1971.

There are a number of remains in the area, as well as the obvious buildings, theres a dam upstream from which a mill race can be traced to the mill.

Monks Walk, Guisborough Priory

This area of the priory is not normally open to the public, but I managed to visit on a Heritage Open Day. The oval avenue of lime trees shows up well on the aerial photos.
