Once through the gate, you're at the star attraction, Daibutsu-den, which is, as you know, the largest wooden building in Japan (and probably the world). It's about five stories tall, and inside is one of the largest Buddha figures, made of bronze. It was built in 752, along with the latest in fire protection technology, those two yellow horns sticking out of the roof that are meant to ward off the fire demons. The hall and the horns continued to be rebuilt after each fire, although the current version, built in 1709, is only 2/3 the size of the original.
