The Parish Church of St. James the Apostle in Gieblo is a 12th-century Romanesque architectural monument, considered one of the oldest rural churches in Lesser Poland. Built in the mid-12th century, it survived practically unchanged until the beginning of the 20th century, when it underwent a thorough renovation. As a result, the chancel was raised and the nave was extended. A new tower was erected, and a brick sacristy was added. The church is surrounded by stone walls dating back to 1787, and the interior was renovated in 1934.
Architecturally, the church is an oriented single-nave structure with a square chancel and features characteristic of the Romanesque style, such as semicircular windows and a pointed tower. The interior is kept in a simple yet elegant style, with flat walls and a choir with an organ. Notable are the three wooden altars, including the main altar with an image of the Merciful Jesus and side altars dedicated to the Virgin Mary and St. Anthony. The tower houses a bell dated to 1825, underscoring the church's historical value.
The church not only constitutes an important element of the region's cultural heritage but also stands as a witness to Gieblo's rich history. Its architecture and furnishings exemplify local craftsmanship and traditions, making it a significant site both for parishioners and tourists interested in the history and culture of Lesser Poland.
