The Church of Great Saint John the Baptist was built as a Gothic style fort-church probably in the end of 13th century but before 1330's. It is a typical Central-Estonian church with three naves. There is a rectangular east choir and tetragonal west tower. The portals of the church are remarkable. During the wars the pillars and arches of the church were destroyed. Supposedly, the church had round pillars. The wooden ceilings were built when the church was reconstructed.
Late baroque organ prospect (by Johann Andreas Stein, 1804) covers the organ made by the Kriisa brothers in 1937. The altar wall dates back to 1870 and was created by Johann Gottfried Mühlenhausen. The altar painting of church is “Jesus Christ on the Cross”. There is a monument of Hans Heinrich von Fersen, a memorial plaque for Alexander von Fersen, and a unique cross from 1598, one of the oldest in Estonia, in that church.
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.
