Keski-Pori Church

St. Olaf's Church in Ulvila is a medieval stone church built between 1495 and 1510. The bell tower was built by J. Winberg of Pori in the 1750s and rebuilt by Georg Theodor Chiewitz in 1862. The church of Ulvila received its first organ in the 1890s.

The Church of the Holy Cross was probably completed between 1515 and 1520 and was originally built as the church of the Franciscan convent in Rauma. The Church of the Holy Cross served as a Franciscan church until 1538 when the monastery was abolished with the Reformation. The paintings in the church date back to the 16th century. The church tower was built in 1816 with stones from the ruins of the former Church of the Holy Trinity. The whitewashed tower was once used as a landmark by sailors. The top of the tower, destroyed by fire, was rebuilt in 1968 from non-combustible materials.

The Huittisten church is a medieval stone church, the oldest parts of which date back to the 1340s. At the end of the 15th century, the central and eastern parts of the church were raised. In the 1630s a tower was built on the west gable and in 1647 the southern part was given a nave. During the 18th century, the church was renovated and rebuilt several times after a fire at the end of the century. The Huittisten church became a cross church in 1860 with the completion of the northern part.
