Helga Trefaldighet (Holy Trinity) Church was inaugurated in 1302. It replaced the previous church of local Ullerås parish. The church is made of grey stone and brick and it was originally a three-nave basilica. The western tower was added in the 15th century. The church was damaged badly by fire in 1702.
The interior is particularly notable. It is decorated with paintings by the famous medieval artist Albertus Pictor, which were created in the second half of the 15th century. Of particular interest is the depiction of The Visitation, regarded as one of the finest surviving medieval paintings in Sweden.
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.
