The Central Gate, Golden Hall and Five-storey Pagoda in Hōryū-ji's Western Precinct, in Ikaruga, date from the Asuka period. The temple was UNESCO-listed in 1993.
Why it's unique
These are the world's oldest surviving wooden structures, and you can walk among them and into the precinct rather than view them from a distance.
The Central Gate's Niō are also Japan's oldest pair, and the Eastern Precinct adds the octagonal Yumedono.
Before you go
Do not skip the Eastern Precinct: the octagonal Yumedono, and Chūgū-ji just behind it with its seated, smiling Bodhisattva (separate ticket). The Yumedono's hidden Guze Kannon is shown only in short spring and autumn windows; check the temple's notices for dates.
