Comer's Midden is the find after which the Thule culture was named. The site was first excavated in 1916 by whaling Captain George Comer, ice master of the Crocker Land Expedition's relief team, and members of Knud Rasmussen's Second Danish Thule Expedition who were in the area charting the North Greenland coast.
The site shows signs of having been inhabited from the 14th to the 20th century although Holtved reports that the 17th and 18th centuries are poorly represented. It contains about 26 house ruins and several middens distributed over an area of about 120 m in width and stretching over 400 m inland with the midden Comer excavated located at its south end. The majority of the houses were more or less rounded, typically around 3m to 5m across and most likely residential. One house was rectangular 4.5m by 6m, with narrow platforms along two of the walls, was probably a 'qassi' or 'men's house' and was probably used as a workshop and for social gatherings.
Subsequent to the initial finds, additional artifacts pertain to the Dorset culture, as well as items of Norse origin. The vast majority of harpoon heads found are of the open socket type typical of the Thule culture.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.
