Malcolm's Tower consists of the foundations of a rubble built, rectangular tower enclosed by an oval shaped modern wall.
The tower stood on a highly defensible peninsular outcrop of rock above a deep ravine and is the site from which the city derives its name. It was effectively the seat of royal power in Scotland after Malcolm III of Scotland shifted the centre of government from Forteviot to Dunfermline in the mid 11th century. The site was also close to a religious centre which had begun as a Culdee establishment in the 9th century. The first mention of the tower in the historical record is from 1070 when Malcolm III married his queen, Princess Margaret. As queen, Margaret introduced innovations which changed the course and identity of the Church in Scotland. Not far to the east of the tower's location are the remains of Dunfermline Abbey and later royal palace.
All that survives of the tower today are foundational fragments of wall, but an image of the building was adopted at an early date as the burgh arms for Dunfermline. Old wax seals suggest it to have been a building of two storeys with an attic. It might have contained around twenty small apartments. Before the western access road to Dunfermline was built, Malcolm's Tower would have been an almost impregnable fortress, perhaps rather like a broch, and this almost certainly explains Dunfermline's motto Esto rupes inaccessa (Be an inaccessible rock).References:
The castle of La Iruela, small but astonishing, is located on the top of a steep crag in Sierra de Cazorla, Segura y Las Villas Natural Park. From the castle, impressive views of the surrounding area and of the town can be enjoyed.
The keep dates from the Christian era. It has a square base and small dimensions and is located at the highest part of the crag.
There are some other enclosures within the tower that create a small alcázar which is difficult to access.
In a lower area of the castle, protected with defensive remains of rammed earth and irregular masonry, is an old Muslim farmstead.
After a recent restoration, an open-air theater has been built on La Iruela castle enclosure. This theater is a tribute to the Greek and Classic Eras and holds various artistic and cultural shows throughout the year.
The first traces of human activity in La Iruela area are dated from the Copper Age. An intense occupation continued until the Bronze Age.
Originally, La Iruela (like Cazorla) was a modest farmstead. From the 11th century, a wall and a small fortress were built on the hill to protect the farmers.
Around 1231, don Rodrigo Ximénez de Rada, Archbishop of Toledo, conquered La Iruela and made it part of the Adelantamiento de Cazorla. Over the Muslim fortress, the current fortress was built.
Once the military use of the fortress ended, it was used as cemetery.
