I got speaking to a couple from near Geneve, (actually he was from England and she from Canada) in the Jahangir Palace. We were discussing the subject of Health and Safety and the lack there of within the palace as there were sheer drops off the side of the upper storey and loads of simply looking bamboo scaffolding up the sides of towers and such like. Just as we were joking about the subject, the piece of stonework he was leaning against suddenly gave way and moved to the side taking him with it. Luckily it only moved about a foot to the side and not fully over otherwise he would've fallen down to the ground floor. Another area to be weary is on top of the Unth Khana (camel house) where you can walk on the roof and there's nothing to stop you from falling off the edge. Be careful when walking around as things that look unsafe invariably are.
As with a lot of palaces and forts I visited in India, I saw huge nests of wasps attached to the underside of ledges etc of the places. While they won't really annoy you, you still need to be aware of them and don't disturb them.
Mange and lice are not strange to these dogs. They live inside the palaces and often are aggressive towards a passer-by.
Do not feed them, because they won't leave you alone for a while...
