The ruins of Jesus de Tavarangue are an important Jesuit mission site located in the Itapúa department of Paraguay, near the town of Trinidad. The mission was founded in 1685 and operated for nearly 150 years until it was abandoned in the early 19th century.

The site is renowned for its impressive architecture and is considered one of the finest examples of the Jesuit missions in Paraguay. The mission's church is a large, baroque-style structure that is adorned with intricate carvings and features an impressive facade.

In addition to the church, the site also features a number of other buildings, including a residential area, workshops, and a hospital. Many of these buildings are still largely intact, and visitors can explore the site to get a glimpse of what life was like for the Jesuits and the Guarani people who lived and worked there.

The ruins of Jesus de Tavarangue have been designated a UNESCO World Heritage Site as part of the Jesuit Missions of La Santísima Trinidad de Paraná and Jesús de Tavarangue, a group of missions that includes several other sites in Paraguay and neighboring Brazil and Argentina. The site is an important cultural and historical landmark, and a must-visit destination for anyone interested in the history of the region.
