The island of Gaddtarmen (Hauensuoli, The Pike´s Gut) off Hanko forms a natural harbour on a sailing route in the east-west direction. Sailors have made more than 600 carvings on the rocks while awaiting favourable winds. The oldest drawings date from the 15th and 16th centuries. Most of the carvings decpict coats of arms of Swedish and Finnish gentry. Probably the most famous carving was made in 1754 by Field Marshal Augustin Ehrensvärd, the originator of Suomenlinna sea fortress.
The site is a unique document relating to the history of the Baltic Sea. It’s added to the tentative list of Unesco World Heritage Site by the National Board of Antiquities.
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.
