Construction of the Tui Cathedral began in 1120, but it was not consecrated until 1225 under the reign of Alfonso IX. It looks like a fortress because of its crenellated towers. Its structure is clearly Romanesque and later diverse decorative Gothic elements were added. From the Romanesque period there are the capitals that top the interior columns, and from the Gothic period there is the portico of the main entrance.
The main chapel located in the choir was completed in 1699 by Castro Canseco. The interior has a large prominent retablo de la Expectacion, and a large altar of relics in the Chapel of the Relics.
Doune Castle was originally built in the thirteenth century, then probably damaged in the Scottish Wars of Independence, before being rebuilt in its present form in the late 14th century by Robert Stewart, Duke of Albany (c. 1340–1420), the son of King Robert II of Scots, and Regent of Scotland from 1388 until his death. Duke Robert"s stronghold has survived relatively unchanged and complete, and the whole castle was traditionally thought of as the result of a single period of construction at this time. The castle passed to the crown in 1425, when Albany"s son was executed, and was used as a royal hunting lodge and dower house.
In the later 16th century, Doune became the property of the Earls of Moray. The castle saw military action during the Wars of the Three Kingdoms and Glencairn"s rising in the mid-17th century, and during the Jacobite risings of the late 17th century and 18th century.
