Jokioinen manor was established in 1562 when Erik XIV, the king of Sweden, donated the area as fiefdom to Klas Kristersson Horn. The heyday of Jokioinen manor was in the 18th century at the time of R.H. Jägerholm (he bought the manor in 1752), when the manor owned 32000 hectares land around the Jokioinen. After him several famous families have owned Jokioinen including Flemings, Jägerhorn af Spurilas, Reuterholms, von Willebrands sekä Mannerheims.
The present manor house was built in 1794. With 30 rooms it was then second largest building in Finland. The garden is from the 17th century. Today it is owned by the MTT Agrifood Research Finland. The manor outdoor areas are open to the public.
The city walls of Avila were built in the 11th century to protect the citizens from the Moors. They have been well maintained throughout the centuries and are now a major tourist attraction as well as a UNESCO World Heritage Site. Visitors can walk around about half of the length of the walls.
The layout of the city is an even quadrilateral with a perimeter of 2,516 m. Its walls, which consist in part of stones already used in earlier constructions, have an average thickness of 3 m. Access to the city is afforded by nine gates of different periods; twin 20 m high towers, linked by a semi-circular arch, flank the oldest ones, Puerta de San Vicente and Puerta del Alcázar.
