Saint John the Baptist church in Orneta, Gothic church in Orneta, Poland.

Saint John the Baptist church is a Gothic brick basilica with a 45-metre tower on its west side, built on a square plan and set into the main body. It has three naves and four bays, with no separate chancel or choir, and the central nave is much higher than the aisles. Eight chapels open onto the aisles, and the outer walls carry a wide glazed-brick frieze from 1390–1450 with reliefs of male and female heads.

Construction began under Warmian bishop Herman of Prague, who resided at Orneta castle, and the church was consecrated in 1379 by bishop Henryk III Sorbom. From 1394 chapels were added to the aisles, and in 1494 it was reconsecrated under Saints John the Baptist and John the Evangelist. After a fire in 1730 the interior received Baroque furnishings.

The church is dedicated to Saint John the Baptist and Saint John the Evangelist, a double patronage given at its re-consecration in 1494. Its side altars include one to Saint Elizabeth of Hungary, the patron saint of Orneta, and a Rococo altar of the Virgin of the Rosary made in 1761 by Christoph Perwanger of Tolkmicko.

The church is located in the center of Orneta, within walking distance from the town square and main streets. As an active place of worship, visiting during a service or checking ahead about opening hours will ensure you can step inside and see the interior.

The exterior walls carry a wide band of glazed brick laid between 1390 and 1450, set in several tiers and carved with reliefs of male and female heads facing the street. The church also keeps Gothic wall paintings from the 14th and 15th centuries, among them the Coronation of the Virgin from about 1380, hidden behind the Holy Family altar.
