A lot of the buildings at Eastern United are still standing,some are being used for other businesses,not sure if the Baths are still there,or what condition they are in if so.
Just look at the Stone buildings on the Old Collieries we had in South Wales,pure craftmanship,but mostly gone under the bulldozer
Although a Brick building,Crumlin Navigation in Crumlin is worth a look at,good photo`s on the Welshcoalmines site to give you an idea of the quality workmanship,even though listed,its sadly left to decay.
