Horyu-ji is a Buddhist temple located in Ikaruga, Nara Prefecture, Japan. It is one of the oldest wooden structures in the world, dating back to the 7th century, and is designated as a UNESCO World Heritage Site.

The temple was founded in 607 by Prince Shotoku, who played a key role in the introduction of Buddhism to Japan. It was originally called Ikaruga-dera, but its name was later changed to Horyu-ji, which means "Temple of the Flourishing Law." The complex includes a large pagoda, a main hall, a lecture hall, and numerous smaller buildings.

The main hall, or Kondo, houses some of the oldest surviving wooden statues in Japan, including a statue of Shaka Nyorai, the historical Buddha. The pagoda, which stands at 32 meters tall, is one of the oldest wooden structures in the world and is an important example of East Asian architecture.

Horyu-ji also has a large collection of art and artifacts, including paintings, sculptures, and calligraphy, many of which are designated as national treasures or important cultural properties.
