Iglesia de San Esteban Protomártir, Baroque church in Fuenlabrada, Spain.

The Iglesia de San Esteban Protomártir is a baroque church featuring a Latin cross floor plan with a semi-octagonal apse and a barrel vault covering the main nave. This vaulted ceiling creates the defining spatial character of the interior throughout the worship area.

The parish archive burned, so the exact construction date is unknown, but the church is cited in a 1427 manuscript of visitations by the cleric Martín Sánchez. The oldest surviving remains, the apse and tall buttresses, date from the first half of the 16th century, and the building was completed during the 17th century. A munitions depot explosion during the Civil War damaged the main facade and part of the nave; reconstruction began in 1945, and Archbishop Casimiro Morcillo reopened the church on 12 May 1950.

The main altarpiece displays a canvas depicting the martyrdom of Saint Stephen and reflects the artistic sensibility of early 18th-century religious commissions. The side altars similarly showcase religious artistry that gives visitors insight into baroque devotional practices.

The church stands on the Plaza de Francisco Escolar in the old town, the same square where the parish has stood since before 1427. Visitors enter through the main facade, rebuilt after the 1936 munitions explosion, and face the short transept and semi-octagonal apse. The 1950 tower and the 1945 reconstruction define the exterior seen today.

The two carvings of Saint Isidore the Farmer and Saint Joseph flanking the main altar survived the Civil War fire and are among the few pieces saved from the 1930s destruction. The parish archive also burned, which is why the building's exact construction date remains unknown.
