The Church of All Saints in Blizne is a Gothic wooden temple, likely built before 1470, renowned for its rich furnishings and unique architecture. Situated on a hill and surrounded by ancient trees, it is an example of wooden sacral architecture in Poland and part of the Wooden Architecture Trail of the Podkarpackie Province. In 2003, the site was inscribed on the UNESCO World Heritage List, confirming its significance. The church is constructed using fir logs in the log technique and features a structure based on a medieval tie-beam, collar-beam, and clasping system. Its single-space nave is nearly square in shape, while the narrower chancel ends in three sides. The dominant architectural element is the post-and-frame tower. The interior of the church is adorned with a valuable set of polychromes from 1549, 1649, and 1700, which were restored in 2000–2001. Among the furnishings, the 17th-century main altar, late Baroque side altars, the pulpit, and the wooden baptismal font stand out. It is worth noting that all windows are placed only on the southern side, giving the interior a unique character. The church is an important center of worship, especially due to the statue of the Virgin Mary Full of Grace, venerated by the faithful. Surrounding the church are a wooden fence and parish buildings, including a parish museum. Due to its excellently preserved structure and exceptional artistic value, the site attracts the attention of tourists and historians. An interesting fact is that a significant renovation was carried out in 1811, and the site underwent restoration in the 1960s and 1990s, indicating systematic care for cultural heritage.
