I recently visited a 'heritage' site (Beamish Museum) and entered the drift mine.
Hard hats were issued to all visitors (to the mine) and I soon discovered why.
I am not tall, but nevertheless it wasn't long before my hat was striking the roof (even though I was stooping to avoid the obvious lack of clearance) - sometimes with enough impact to arrest my progress.
Apparently the height of the passageways was determined by the height of the ponies that pulled the trucks.
