Tyrvä

Tyrvää is a former municipality located in the Satakunta region of Finland. It was established in 1869 and merged with the municipality of Vammala in 1973. Vammala itself was later consolidated with other municipalities to form the modern city of Sastamala in 2009. During its existence as an independent municipality, Tyrvää encompassed a significant rural area with a notable historical center.

The town of Tyrvää, which served as the administrative center, is known for its medieval stone church, Saint Olav's Church. This church is one of the most important historical buildings in the region. The area was also historically important for trade and crafts. Tyrvää's economy was primarily based on agriculture and small industries. The landscape of Tyrvää was characterized by forests, lakes, and cultivated fields, typical of the Finnish countryside. The legacy of Tyrvää continues within the municipality of Sastamala, particularly through its historical sites and cultural heritage.
