The museum has been closed for a while due to… a fire. :( Fortunately not too much damage was done and they say it will reopen at some undefined point in the future.
The Subway has recently been refurbished and looks nice. :) https://www.crystalpalaceparktrust.org/pages/crystal-palace-...
The dinos are getting a bit of love too at the moment it seems (was there last weekend and there is some construction going on the island and the lake around it.
It’s a very nice park to visit. :)
