The construction of the church of St. John in Unikowo was probably started shortly after the location of the village in 1367, the work probably lasted between 1370 and 1380. Before the end of the fourteenth century, the upper part of the tower was built, which was initially timber. The church was renovated in 1850, when the gables of the tower were reconstructed.
The church was erected as a building orientated towards the sides of the world, on a rectangular plan, without an externally separated chancel. From the north a sacristy, from the south a porch and a square, three-storey tower from the west were added. Its floors have been distinguished with plastered friezes, and the walls were decorated with ogival blendes. A similar plasterwork frieze decorated the remaining façades. The corners of the nave were reinforced with diagonal buttresses and the walls were pierced with ogival windows. The tower and the nave were crowned with gothic stepped gables with pinnacles, of which the tower’s gable is a 19th-century reconstruction. The nave and the porch were covered with a timber, flat ceiling and the sacristy with a barrel vault.
