Petra is a quiet country town 43 kilometers from Palma de Mallorca and is listed as a Property of Cultural Interest. The most important sight is the convent where Friar Junípero went to school. 

The town also has an excellent museum that illustrates the life and work of Friar Junípero Serra, who was born in Petra.

 Another tribute to the famous missionary is the festival held every year on the third Sunday of September. This lively event features parades with impressive floats and colorful floral offerings.

Other interesting monuments in Petra include the Iglesia de San Pedro, a Gothic church with a fortress-like facade; the Convento de Sant Bernardí, a peaceful retreat created for the Franciscans; and the Santuario de Nostra Senyora de Bonany (Sanctuary of Our Lady of Bonany), a Neo-Baroque church that presides over a hilltop.
