late Gothic Castle Semple Collegiate Church is under the protection of Historic Environment Scotland as a Scheduled monument.
John Sempill, 1st Lord Sempill founded the collegiate church near Castle Semple, in circa 1504. It had a provost, six chaplains or prebendaries, two boys, and a sacristan. The roof was removed in the 1800s, and the ivy has penetrated into the interior. The building is a simple oblong, terminating toward the east in a three-sided apse, and having a square tower projecting from the centre of the west wall. The forms of the double windows indicate that they are very late survivals of Gothic architecture. The other windows in the side walls are altered, but they do not present any features like those of the apse.
Over the door to the chancel are two coats of arms with the letters R. L. S. and A. M. S., one shield bearing the Sempill arms and the other those of Montgomerie. The square tower at the west end is extremely simple. The tower and most of the side walls are of about the date of the original foundation, while the east apse has been added in the 16th century, to receive the monument of John, Lord Sempill, who died at the Battle of Flodden in 1513. A few remains of the original squareheaded windows in the side walls are still traceable. The interior was divided by two solid walls into three compartments, so as to form separate private burial places. In the eastern compartment, there is a large monument to Lord Sempill. A monumental slab in the central compartment is erected in memory of Gabriel Sempel, who died in 1587.References:
The Palace of the Kings of Navarre of Olite was one of the seats of the Court of the Kingdom of Navarre, since the reign of Charles III 'the Noble' until its conquest by Castile (1512). The fortification is both castle and palace, although it was built more like a courtier building to fulfill a military function.
On an ancient Roman fortification was built during the reign of Sancho VII of Navarre (13th century) and extended by his successors Theobald I and Theobald II, which the latter was is installed in the palace in 1269 and there he signed the consent letter for the wedding of Blanche of Artois with his brother Henry I of Navarre, who in turn, Henry I since 1271 used the palace as a temporary residence. This ancient area is known as the Old Palace.
Then the palace was housing the Navarrese court from the 14th until 16th centuries, Since the annexation (integration) of the kingdom of Navarre for the Crown of Castile in 1512 began the decline of the castle and therefore its practically neglect and deterioration. At that time it was an official residence for the Viceroys of Navarre.
In 1813 Navarrese guerrilla fighter Espoz y Mina during the Napoleonic French Invasion burned the palace with the aim to French could not make forts in it, which almost brought in ruin. It is since 1937 when architects José and Javier Yarnoz Larrosa began the rehabilitation (except the non-damaged church) for the castle palace, giving it back its original appearance and see today. The restoration work was completed in 1967 and was paid by the Foral Government of Navarre.
