First record of Hatanpää dates back to year 1540 and the first manor was built in the 1690s. Hans Boije (1717-1781) improved the farming business and increased Hatanpää prosperity significantly. He also built an English garden to Hatanpää with and hired 30 gardeners to maintain it. Boije was a freemasonry and added an stone to the park with Greek engraving Egno Kyrios tous ontas antou (Lord knows his owns). The stone still exists and is known as the “grave of the freemasonry”, but no one is actually buried there.
After Boije Hatanpää manor has been owned by several families. The original main building burned in 1883 and the present one Neo-Renaissance manor was built in 1883–1885. There’s also an another Neo-Gothic manor nearby. It was built in 1898-1900 as the villa for the banker and manor owner Nils Idman. Idman was forced to sell all Hatanpää manor property to the city of Tampere in 1913. The manor was in hospital use until the new hospital was built nearby in 1930s.
Today Hatanpää manor can be booked for parties or conferences. Near the manor are beautiful rose garden and arboretum, which are very popular in the summer time.
The small Grisslehamn village is today a well-preserved sample of 19th century architecture and popular attraction for daily trips. The name Grisslehamn was first mentioned in a document from 1376 about the mail route between Sweden and Finland. This Grisslehamn was located some 20 km south of today's location. In the mid-18th century, most of the old village was destroyed in a fire, and it was decided to move Grisslehamn to its current location to make the mail route shorter. Conveying mail by row boat from Sweden to Åland, from whence it was transported to the Finnish mainland, was, together with fishing, one of the most important sources of income for the inhabitants of Grisslehamn and other parts of Roslagen for a long time, until steam ships took over the mail routes in the early 20th century.
During the Finnish War in 1809 a small unit of Russian cossacks attacked to Grisslehamn over the frozen Gulf of Bothnia. In the battle 80 Swedish soldiers surrended and several were killed.
Today there are several buildings dating from the 19th century, like the toll station and old barracks. The post office was built in 1755 and the chapel in 1909.
