The site is so huge, it would take all day to walk around and see everything. Luckily you can hop on and off the vintage trams and buses which run around the site, from the farm, to the hall, to the pit vallage, and to the jewel of the site, the town.
The buildings and displays represent life during Georgian, Victorian and Edwardian times, and everywhere there are people in period costume demonstrating life in the apropriate times of the buildings.
I could write a book on the experiences to be had, but you really need to visit it yourself. So, for now, I'll just post a few pictures:
This is Flash - a little pit pony from the colliery village. These tiny ponies could pull many times their own weight, and were the only way to transport coal to the surface in the days before mechanisation.
