Close by the Jadro, to the east of Salona, there are remains of churches on the site known for centuries by the local people by the true, descriptive name of Šuplja crkva (Hollow Church). The name originates from the time when here there were walls of an unattended church with a collapsed roof, recorded on the Camuci’s map of 1571. Remains of a three-aisled basilica, dedicated to Ss. Peter and Moses appear to have existed at the end of the 17th and the beginning of the 18th centuries, when the newly arrived inhabitants of Solin named them so picturesquely. The church is from the 11th century, linked with the coronation of Zvonimir as a Croatian king in 1075, built within a large early-Christian basilica, probably from the 6th century. Next to the church, there was a Benedictine monastery, possibly connected with the dynasty, which is a possible reason why the new church was built within the old one, to become the site of such an important event. This fact has made this early-Romanesque three-aisled basilica particularly famous.
Today, the landscape differs very much from the landscape of the early-Christian time and the 11th century. The river flowed down a completely different bed, and the surrounding terrain was lower. The river nowadays flows close to the site, flooding the old walls remains that, due to the new configuration of the surrounding land, often remain under water. This is an excellent and very clear example of how the small Jadro has gradually changed the configuration of the landscape of the Solin’s monuments.
The three-aisled basilica had a specific western façade, the so-called westwerk, and a bell tower, and three apses incorporated right into the church body at its eastern end. In the church, there was a large, three-part altar screen, bearing the inscription that revealed its titulars, Ss. Peter and Moses (sv. Petar i Mojsije), and, with help from written historic sources, the course of important historic events, as well. Some scientists believe that parts of the altar screen were also the slabs that now make the baptismal font in the St. John’s Baptistery of Split, including the famous slab usually interpreted as presenting an enthroned Croatian king.
References:First record of Kastelholma (or Kastelholm) castle is from the year 1388 in the contract of Queen Margaret I of Denmark, where a large portion of the inheritance of Bo Jonsson Grip was given to the queen. The heyday of the castle was in the 15th and 16th centuries when it was administrated by Danish and Swedish kings and stewards of the realms. Kastelhoma was expanded and enhanced several times.
In the end of 16th century castle was owned by the previous queen Catherine Jagellon (Stenbock), an enemy of the King of Sweden Eric XIV. King Eric conquered Kastelholma in 1599 and all defending officers were taken to Turku and executed. The castle was damaged under the siege and it took 30 years to renovate it.
In 1634 Åland was joined with the County of Åbo and Björneborg and Kastelholma lost its administrative status.
