There has been a wooden church in Källa since the 11th century. After it was destroyed by fire, and with increasing attacks from Baltic invaders, a new church of stone - with the aspect of a fortress - was constructed in stages was built in the 13th century. The two-storied construction, dedicated to St. Olav, was very unusual and made for defensive purposes.
The Källa Church fell into disrepair when a new church was built here in the nineteenth century, but has now been taken into the care of the National Heritage Board and is a major tourist attraction. The most valuable of the old Källa Kyrka's furnishings, including the 15th-century triptych carving and the pulpit from 1600, were moved to the new church.
In the churchyard many of the huge old flat gravestones date from the 1600's and 1700's. Older graves have been discovered from the 11th and 12th centuries.
References:The Villa d'Este is a 16th-century villa in Tivoli, near Rome, famous for its terraced hillside Italian Renaissance garden and especially for its profusion of fountains: the extraordinary system contains fifty-one fountains and nymphaeums, 398 spouts, 364 water jets, 64 waterfalls, and 220 basins, fed by 875 meters of canals, channels and cascades, and all working entirely by the force of gravity, without pumps. It is now an Italian state museum, and is listed as a UNESCO world heritage site.
Tivoli had been a popular summer residence since ancient Roman times due to its altitude, cooler temperatures and its proximity to the Villa Hadriana, the summer residence of the Emperor Hadrian I.
The Villa was commissioned by Cardinal Ippolito II d'Este (1509-1572), second son of Alfonso I d'Este, the Duke of Ferrara and grandson of Pope Alexander VI, along with Lucrezia Borgia.
