Make sure you go to the Natural History Museum, it has items of great age, but more important, you can get up close and personal with them. Not standing 6 ft away behind glass. Very few of the items are off limits. But please use common courtesy and don’t damage or defile them.
So much stuff that even the gardens seem to be filled with the items they didn’t have room for in the museum. We are talking 1000 bc type stuff!
