Traquair House is claimed to be the oldest continually inhabited house in Scotland. Whilst not strictly a castle, it is built in the style of a fortified mansion. It pre-dates the Scottish Baronial style of architecture, and may have been one of the influences on this style. The estate contains the famous Traquair Brewery.
The house is built on the site of a hunting seat used by the Scottish kings from the 12th century, though no part of the present building can be dated with certainty before the 15th century. Alexander I was the first Scottish king to stay and hunt at Traquair.
Over the next two centuries Traquair's ownership changed often, at times coming under the control of the English, and at others, the Scottish throne. Traquair remained the family seat of the Earls of Traquair from 1491 for the next four centuries.
Traquair is a 50-room house mainly dating from teh 16th-19th centuries. There is a Roman Catholic chapel built in 1829, following the Catholic emancipation. The 18th-century library contains more than 3,000 volumes. Although three lairds made alterations to the house prior to the 17th century, Traquair has changed little, architecturally, since then.
References: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.
