Igreja Ortodoxa Sao Jorge, Orthodox Church in Lago Sul, Brazil

Igreja Ortodoxa São Jorge is a cylindrical building 30 metres in diameter and about 7 metres high, painted white and crowned by a dome, designed by Oscar Niemeyer. The worship space occupies the upper level, reached by an external curved ramp, while the ground floor holds the parish hall with its own entrance. A beam links the bell tower to the main volume, forming a portico that marks the entrance and braces the ramp.

Construction began on June 8, 1993, based on a design from 1986 by architect Oscar Niemeyer, and was completed by February 11, 1994. The relatively quick completion showed the community's commitment to establishing their spiritual center.

The Orthodox community here traces back to Syrian and Lebanese immigrants who arrived in the region during the mid-1950s seeking to establish their faith. Today, the church serves as a spiritual center where the community gathers to practice Byzantine traditions and celebrate their religious calendar.

Entry to the worship space is via an external curved ramp that eases access to the upper level. The separate arrangement of the parish hall on the lower level allows different groups to gather without interfering with worship services.

The building employs a sophisticated zenital lighting system that channels natural light through narrow openings directly onto the main altar. These same openings serve dual purposes, also providing ventilation that keeps the interior fresh and comfortable.
