San Cosme y Damián: Mission, Stars and Paraná

San Cosme y Damián brings together themes you can prioritize differently on a trip: the former Jesuit mission, astronomy, and waterscapes along the Río Paraná and in the Yacyretá Reservoir. The mix ranges from historic buildings and celestial models to white sand formations and seasonal activities along the riverbank. You can shape your trip to suit your interests in culture, science, or water.

The Jesuit Mission and the History of Astronomy

The former Misión Jesuítica de San Cosme y Damián is considered one of Paraguay’s best-preserved missions; its condition is described as excellent. The church of the reduction was damaged by a fire in 1899 and restored in 1977 with support from Adveniat and the Archdiocese of Cologne. Alongside preserving the former mission, the focus also includes specific milestones in its history.

The history of astronomy also includes the work of Padre Buenaventura Suárez and Indigenous people: together, they built a rudimentary telescope, an astronomical quadrant, and a sundial. These instruments give the astronomy theme a historical dimension that extends beyond observing the sky today.

The Astronomical Interpretation Center

The Centro de Interpretación Astronómica Buenaventura Suárez is located at the mission. There, you can explore a scale model of the solar system. The observatory has solar telescopes and night-sky telescopes for observing the sky by day and by night.

A gnomon is used to measure solstices and equinoxes. An armillary sphere illustrates the Earth’s movement around the Sun. The center also includes a galaxy slide depicting our galaxy with a black hole at its center, and a screening room devoted to Guaraní astronomy. The models, measuring instruments, and displays each highlight different aspects of the sky.

White Dunes and the Paraná Riverbank

The Dunas de San Cosme y Damián are white sand formations in the Yacyretá Reservoir and can be reached by boat. Specific arrangements for boat access may vary. This dune landscape differs from the banks of the Río Paraná, where Playa Municipal de San Cosme y Damián is a recreational area.

During the summer season, Playa Municipal is a gathering place for leisure activities, water sports, and community events. This seasonal character is relevant to your planning; individual events and conditions may vary. Thus, the waterside features both a reservoir area with white sand formations and a seasonal area along the riverbank.

When choosing a holiday apartment in San Cosme y Damián, your preferred focus can be the deciding factor: are you mainly interested in mission history and astronomy, or would you like the two waterscapes to play a bigger part in your trip? If you want to include seasonal activities at the beach, the summer season is also something to consider. This way, you can tailor your search to the themes you want to explore during your stay.

Nature in the Surrounding Area

In the surrounding area, a section of the trail in the Guasu Puku Nature Reserve crosses a natural watercourse via a suspension bridge. This stretch of trail adds another natural feature alongside the mission, astronomy, and waterscape themes.
