Orkesta Church in Vallentuna was built in the late 12th century and the the eastern part of original nave remains. The sacristy and southern nave were added in the 15th century. The round window was added in 1750.
The crucifix was carved between 1325-1350. The rococo style pulpit was added during the restoration in 1753. The external wooden belfry was erected in the 17th century.
According a legend, King Gustav Vasa of Sweden was born in the church. The near Lindholmen farm was owned by Vasa family in the late Middle Ages.
The Orkesta Runestones are a set of 11th-century runestones engraved in Old Norse with the Younger Futhark alphabet that are located at the church of Orkesta.
Several of the stones were raised by, or in memory of, the Swedish Viking Ulf of Borresta, who during the 11th century returned home three times with danegeld. The leaders of the three expeditions were Skagul Toste (Tosti), Thorkell the Tall (Þorketill), and Canute the Great (Knútr). This Ulfr also made the Risbyle Runestones in the same region, and he was mentioned on the lost runestone U 343.
The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
