Illens Castle

Rossens, Switzerland

The ruins of Illens castle stand on a rock wall above a loop of the Saane river. The castle stands on the opposite side of the river from the fortified town of Arconciel. The two castles secured both sides of a crossing (either a ford or a bridge) over the river. The castle is first mentioned between 1150 and 1276.

In 1366, the notoriously violent Count Peter of Aarberg moved into the castle and remained there for a short while. The chamberlain of Charles the Bold, Guillaume de la Baume, expanded the castle and when he left in 1470, it was an elegant and comfortable palace. During the conflicts leading up to the Burgundian Wars, Fribourg and Bernese troops stormed and damaged the building on 3 January 1475.

In 1900, it was partly repaired and expanded and served a community of Trappist monks.

31.08.2022. What a pleasure to discover this magnificent place in the canton of Friborg overlooking the Sarine and this mansion under renovation thanks to an association of volunteers. It is certain that I would come back there if only to meditate and dawdle listening to the song of the birds or the knock knock of the woodpecker.

A very nice place for a short walk in the forest, a picnic near the ruins or very close to the water ??? Free parking next to the farm.

A magnificent place! Even though we couldn't get in because it's being renovated, I find its ruins splendid! Congratulations to those who funded the renovation of this place. The renovation is really well done. They are also redoing the floor. I look forward to being able to visit the interior. There are also picnic tables for resting. To visit and study!

Santa Maria in Trastevere

The Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I. 

The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.

The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
