The medieval castle of Häme is located on the coast of lake Vanajavesi. It was originally located on an island.
The castle's age is disputed. Traditionally the construction of the castle has been connected to the legendary Second Swedish Crusade which would date the castle in the mid-13th century. However, there are no finds from the castle that can be firmly dated to a period earlier than 1320s. Also the contents of the crusade legend have been seriously contested. An earlier fortification from about 1300 only some 20 kilometres away in Hakoinen also makes a 14th century dating for Häme Castle more probable. Only one castle ("Tauestahus") is listed in Tavastia in a royal document from 1308. Also, the Russian Novgorod Chronicle only mentions one castle during their plundering of Tavastia in 1311, its description matching well with the castle in Hakoinen.
The construction of Häme castle probably started after the Novgorod invasion. The first castle was made of gray stone, and later bricks were used.
The castle lost military importance by the end of the 16th century. Its defensive systems were upgraded in the 18th century with bastions around the castle. The castle became a prison in the 19th century and served as such until 1953, when massive restoration work started. The castle has been a museum since 1988. Facilities can also be rented for private events.
Easter Aquhorthies stone circle, located near Inverurie, is one of the best-preserved examples of a recumbent stone circle, and one of the few that still have their full complement of stones. It consists of a ring of nine stones, eight of which are grey granite and one red jasper. Two more grey granite stones flank a recumbent of red granite flecked with crystals and lines of quartz. The circle is particularly notable for its builders' use of polychromy in the stones, with the reddish ones situated on the SSW side and the grey ones opposite.
The placename Aquhorthies derives from a Scottish Gaelic word meaning 'field of prayer', and may indicate a 'long continuity of sanctity' between the Stone or Bronze Age circle builders and their much later Gaelic successors millennia later. The circle's surroundings were landscaped in the late 19th century, and it sits within a small fenced and walled enclosure. A stone dyke, known as a roundel, was built around the circle some time between 1847 and 1866–7.
