I have driven this road between intersection of Highway 1 and Aura many times, when we were travelling to Säkylä, as we wanted to explore the roads out of the highway or main road level.
Seututie 224 is a regional road that runs from Aura via Tarvasjoki and Marttila to Salo in the province of Varsinais-Suomi. The length of the road is 43 kilometers.
The area was initially a part of the Lieto parish. A church was built in the village of Prunkkala in 1636, forming a new chapel community. In 1908, an order to separate Prunkkala from Lieto was made. The villages of Kuuskoski, Hypöinen, Viilala and Lahto were transferred to it from Pöytyä. The parish became fully independent in 1917 under the current name Aura, after the Aura train station and the community that had formed around it in the late 19th century
