You're absolutely right
@EbbwJunction1, Ross Castle was built in Cleethorpes by the Manchester Sheffield & Lincolnshire Railway in 1885.
From what I can gather, being local to the area (and so perhaps having a slight advantage of access to local handed down knowledge), it was built when Pier Gardens were made in the area near to the Pier. However there was a steep bank of ground, almost cliff-like in nature, which would otherwise have been quite difficult to access to make the most of the views at the top. Being keen to continue making the area attractive to visitors wishing to savour those views, the idea of a folly made like castle ruins was somehow born to make this area accessible.
I must confess, I didn't realize it would be quite so cryptic, but at the same time it's been great to see the ideas and possibilities coming forward. Well done everyone.
