Tramontano Castle, begun in the early 16th century by Gian Carlo Tramontano, Count of Matera, is probably the only other structure that is above ground of any great significance outside the sassi. However, the construction remained unfinished after his assassination in the popular riot of 29 December 1514.
It has three large towers, while twelve were probably included in the original design. During some restoration work in the main square of the town, workers came across what were believed to be the main footings of another castle tower. However, on further excavation large Roman cisterns were unearthed. Whole house structures were discovered where one can see how the people of that era lived.
The stone church of Gamla Uppsala, built over the pagan temple, dates from the early 12th century. Due to fire and renovations, the present church is only a remnant of the original cathedral.
Before the arrival of Christianity in Sweden, Gamla Uppsala was the seat of Swedish kings and a ceremonial site known all over northern Europe. The settlement was home to royal palaces, a royal burial ground, and a great pagan temple. The Uppsala temple, which was described in detail by Adam of Bremen in the 1070s, housed wooden statues of the Norse gods Odin, Thor and Freyr. A golden chain hung across its gables and the inside was richly decorated with gold. The temple had priests, who sacrificed to the gods according to the needs of the people.
The first Christian cathedral was probably built in the 11th century, but finished in the 12th century. The stone building may have been preceded by a wooden church and probably by the large pagan temple.
