The Archaeological Museum in Zagreb has over 450,000 varied artifacts and monuments, gathered from various sources but mostly from Croatia and in particular from the surroundings of Zagreb.
The archaeological collection of the State Institute had been kept in the Academy mansion at Zrinski Square from the 1880s and remained there until 1945, when the museum moved to its current location at the 19th-century Vranyczany-Hafner mansion, 19 Zrinski Square.
The museum consists of five main sections: Prehistory, Egypt, Antiquity, Middle Ages, Coins and Medals. The section 'Prehistory' contains 78,000 objects, ranging from the Paleolithic to the Late Iron Age. The section 'Egypt' displays about 600 objects in the permanent exhibition. The section 'Antiquity' contains an important collection of Greek vases (about 1,500 vessels) and stones with inscriptions.
The Roman Antiquity is represented by many statues, military equipment, metal objects, Roman religion and art and objects from everyday life, acquired through systematic archaeological excavations in various Croatian regions in many Croatian cities founded during the Roman Empire. The numismatic section is among the largest collections of this type in Europe.
Some of the famous artifacts include Vučedol dove, a flagon shaped as a bird, Liber Linteus, 3rd century BCE mummy and bandages with the longest Etruscan inscription in existence and Lumbarda Psephisma, 4th century BCE stone inscription detailing the founding of an ancient Greek colony on the island of Korčula.References:
Steinvikholm Castle is an island fortress built between 1525 to 1532 by Norway's last Catholic archbishop, Olav Engelbrektsson. Steinvikholm castle became the most powerful fortification by the time it was built, and it is the largest construction raised in the Norwegian Middle Ages.
The castle occupies about half of the land on the rocky island. The absence of a spring meant that fresh water had to be brought from the mainland. A wooden bridge served as the only way to the island other than boat. Although the castle design was common across Europe in 1525, its medieval design was becoming obsolete because of the improved siege firepower offered by gunpowder and cannons.
The castle was constructed after Olav Engelbrektsson returned from a meeting with the Pope in Rome, presumably in anticipation of impending military-religious conflict. As Archbishop Engelbrektsson's resistance to the encroachment of Danish rule escalated, first with Frederick I of Denmark and his successor Christian III of Denmark, Steinvikholm Castle and Nidarholm Abbey became the Catholic Church's military strongholds in Norway. In April 1537, the Danish-Norwegian Reformation succeeded in driving the archbishop from the castle into exile in Lier in the Netherlands (now in Belgium), where he died on 7 February 1538. At the castle the archbishop left behind St. Olav's shrine and other treasures from Nidaros Cathedral (Trondheim). The original coffin containing St. Olav's body remained at Steinvikholm until it was returned to Nidaros Cathedral in 1564. Since 1568 St. Olav's grave in Nidaros has been unknown.
From the 17th to 19th century, the island was used as a quarry and some of its masonry was sold and removed from the site. This activity was condoned by the Danish-Norwegian authorities as a way of eliminating a monument to the opposition of the Danish–Norwegian Union.
Steinvikholm fort is owned and operated today by The society for the Preservation of Norwegian Ancient Monuments. The island has been the site of the midnight opera which details the life and struggles of the archbishop. The opera is held in August annually. The opera is organized by Steinvikholm Musikkteater since the beginning in 1993.
