Viljandi castle was one of the strongest castles in Livonia. The construction was started 1224 under Teutonic Order in place of a former hillfort. The crusaders of Sword Brethren conquered the hill fort at the place of later main castle in 1223. A year later, construction of stone fortifications started. Viljandi was chosen as the high seat of the order.
The convent house, a typical form of castle of Teutonic Knights, was erected late 13th – early 14th century. In the following centuries the castle was extended and fortified further. It was badly damaged in the Polish-Swedish wars in early 17th century and not repaired any more. In 18th century, the ruins were used for quarrying stones for construction work in Viljandi.
The first excavations in the castle were performed in 1878–1879. In recent decades, these have turned to almost yearly events. Currently the ruins form a popular resort area just outside of central Viljandi. An open-air stage is located in the former central courtyard.
The Holy Trinity Column in Olomouc is a Baroque monument built in 1716–1754 in honour of God. The main purpose was a spectacular celebration of Catholic Church and faith, partly caused by feeling of gratitude for ending a plague, which struck Moravia between 1713 and 1715. The column was also understood to be an expression of local patriotism, since all artists and master craftsmen working on this monument were Olomouc citizens, and almost all depicted saints were connected with the city of Olomouc in some way. The column is the biggest Baroque sculptural group in the Czech Republic. In 2000 it was inscribed on the UNESCO World Heritage Sites list.
The column is dominated by gilded copper sculptures of the Holy Trinity accompanied by the Archangel Gabriel on the top and the Assumption of the Virgin beneath it.
The base of the column, in three levels, is surrounded by 18 more stone sculptures of saints and 14 reliefs in elaborate cartouches. At the uppermost stage are saints connected with Jesus’ earth life – his mother’s parents St. Anne and St. Joachim, his foster-father St. Joseph, and St. John the Baptist, who was preparing his coming – who are accompanied by St. Lawrence and St. Jerome, saints to whom the chapel in the Olomouc town hall was dedicated. Three reliefs represent the Three theological virtues Faith, Hope, and Love.
Below them, the second stage is dedicated to Moravian saints St. Cyril and St. Methodius, who came to Great Moravia to spread Christianity in 863, St. Blaise, in whose name one of the main Olomouc churches is consecrated, and patrons of neighbouring Bohemia St. Adalbert of Prague and St. John of Nepomuk, whose following was very strong there as well.
In the lowest stage one can see the figures of an Austrian patron St. Maurice and a Bohemian patron St. Wenceslas, in whose names two important Olomouc churches were consecrated, another Austrian patron St. Florian, who was also viewed as a protector against various disasters, especially fire, St. John of Capistrano, who used to preach in Olomouc, St. Anthony of Padua, a member of the Franciscan Order, which owned an important monastery in Olomouc, and St. Aloysius Gonzaga, a patron of students. His sculpture showed that Olomouc was very proud of its university. Reliefs of all twelve apostles are placed among these sculptures.
The column also houses a small chapel inside with reliefs depicting Cain's offering from his crop, Abel's offering of firstlings of his flock, Noah's first burnt offering after the Flood, Abraham's offering of Isaac and of a lamb, and Jesus' death. The cities of Jerusalem and Olomouc can be seen in the background of the last mentioned relief.
