This was one gate into the mill

There have been three Orry Mills in Eaglesham but they have been closed for around 150 years.

Handloom weaving became the main industry until the establishment of a water powered cotton spinning mill in the village in 1791. The Orry mill at its peak employed around 200 people with the machinery at one time driven by a 45 foot diameter cast iron water wheel. The mill burned down and was rebuilt several times before being destroyed by fire in 1876 and was never rebuilt. Without work many of the mill workers drifted away and their homes lay empty. The population of the village dropped from 2,428 in the mid-nineteenth century to 1,075 at the end of the century.
I think there were 3 gates like this and the gateman counted the girls in and out of the mill
