Tensta Church was probably commissioned by a local aristocratic family,[1] perhaps the owners of Salsta manor house,[2] and built during the last years of the 13th century.
[2] Just outside the church is a preserved runestone (Uppland Runic Inscription 1034).
[1][2] The interior of the church is richly decorated with frescos, the oldest of which are signed by the master Johannes Rosenrod in 1437.
In addition, the frescos include a full-figure portrait of Bengt Jönsson Oxenstierna, kneeling in a suit of armour next to his coat of arms.
[1] Bengt Jönsson Oxenstierna was the owner of Salsta manor at the time and for this reason it has been suggested that this is a portrait of the church donor.
