Since the late 18th century, craftsmen began to settle down in Hirvihaara area of Mäntsälä. Artisans there plied their trade until the early part of the 20th century.
Today, there is an open-air museum in the area. Many of its buildings are craftsmen's cottages in their original location; some of them are cottages of similar kind moved there from other parts of Mäntsälä.
The manor house museum is known as the childhood home of Adolf Erik Nordenskiöld, a world-famous explorer and the first man to sail through the Northeast Passage.
Alikartano, formerly known as the Frugård estate, was acquired by the Nordenskiöld family at the beginning of the 18th century.
In old Porvoo, a city district already at the time of Swedish rule, one can still sense the atmosphere of a medieval town. The mosaic-like city plan with its labyrinthine streets and city blocks of various kinds dates back to the Middle Ages.
There are many cafeterias, boutiques and services in the district of Old Porvoo. Its side streets make it is easy to rid one's mind of modern hodgepodge and make us wonder which era we are now in. Among the conurbation, tiny park paradises and paving suitable for meditation are waiting for the visitor.
