Why should you go there and how do you do it right?

The gold find is the real reason to visit. Most of the exhibits come from the crypt of Wat Ratchaburana and other chedis in the Ayutthaya area – treasures buried deep enough to survive the Burmese looting of 1767. Insignia, Buddha statues, votive offerings, and jewelry fragments – the splendor of the finds is so impressive that you can only truly appreciate them when you are standing right in front of them. Video presentations explain the excavations and their history, so you not only understand what you have seen, but also how the treasures came to light.

My tip: Do this first, before visiting the temples. The ruins of Ayutthaya are now just brick walls, and knowing what the interiors of the stupas were like will change your perspective. Part of the museum is currently being renovated, so you'll mainly see the treasury. However, these were recently renovated and are worth the entrance fee anyway. Everything is air-conditioned, which is more important than you might think on a hot afternoon in Ayutthaya.
