Torre de la Compañía, Colonial convent tower in Potosí, Bolivia.

Torre de la Compañía is a colonial convent tower in Potosí featuring three hemispherical domes, five openings, and thirty-two columns arranged in a triumphal arch configuration. The structure sits near Cerro Rico and displays refined stonework from the 18th century with multiple levels rising toward the sky.

Jesuit missionaries built this religious structure in the 18th century as a spiritual center in the silver mining city. The tower also served as a strategic observation point for monitoring mining activities in the surrounding region.

The building is conceived as a triumphal arch with five openings, thirty-two columns and three hemispherical domes. Its name comes from the Jesuits, the Compañía de Jesús, who settled in Potosí in 1577 under fray José de Acosta. The church they began in 1581 collapsed, killing three Jesuits, and the miner José de Quiroz paid 40,000 pesos fuertes to rebuild it between 1700 and 1707.

Visitors can explore around the tower and view its architectural details from various angles, especially the columns and domes. The best time to visit is in the morning or late afternoon when light highlights the stone surfaces.

The church that preceded the tower collapsed because it was poorly built of adobe and brick, killing three Jesuits. The miner José de Quiroz paid for its reconstruction between 1700 and 1707, at a cost of 40,000 pesos fuertes.
