Nuestra Señora de Santa Ana

Nuestra Señora de Santa Ana is a Jesuit mission ruin in Misiones Province featuring preserved stone walls, foundations, and architectural remains from colonial times. The site shows different areas where residential buildings, a chapel, and service structures once stood side by side.

The mission was founded in 1633 as a settlement for the indigenous Guarani people under Jesuit direction. After the Jesuits were expelled from Spanish territories in 1767, the settlement was abandoned and gradually fell into ruin.

The mission complex reveals how European builders and Guarani craftspeople worked together, blending their skills in the stonework and decoration you see today. Walking through the ruins, you notice details that show contributions from both cultures in the construction methods and artistic choices.

The site is open during daylight hours throughout the year, with guided tours available to help you explore the different areas. Wear comfortable shoes and allow time to examine the stone structures and observe the architectural details at your own pace.

The ruins are part of a UNESCO World Heritage site encompassing four Jesuit missions in Argentina, preserving centuries of colonial religious history. This international protection network helps ensure these places survive for future generations.
