Allaman Castle has its origins in the 11 and 12th centuries but the main components were built by Louis, Duke of Savoy, in 1253.
The wealthy Genevan philanthropist Count Jean-Jacques de Sellon, who owned the property until 1839, gave accommodation at the castle to political refugees, such as Napoleon's brother Joseph Bonaparte, Empress Joséphine de Beauharnais, Voltaire, Franz Liszt and George Sand. In 1820 de Sellon founded the Society of Peace, forerunner of the League of Nations and the United Nations Organization (UNO) and in 1830 the First International Peace Summit was held in Château d'Allaman. Since then, the Castle has also been referred to 'The Castle of Peace'. De Sellon was also instrumental in the abolition of the death penalty in Switzerland.
The Castle of Allaman is one of the largest private properties of Switzerland. The estate covers over 33 hectares and offers some 6,200 m2 of living space. The estate is surrounded by private forests, parks, gardens and Grand Cru vine yards. Recently completely restored and transformed, the Castle is owned by a Swiss family.

Trenčín Castle is relatively large renovated castle, towering on a steep limestone cliff directly above the city of Trenčín. It is a dominant feature not only of Trenčín, but also of the entire Považie region. The castle is a national monument.
History of the castle cliff dates back to the Roman Empire, what is proved by the inscription on the castle cliff proclaiming the victory of Roman legion against Germans in the year 179.
Today’s castle was probably built on the hill-fort. The first proven building on the hill was the Great Moravian rotunda from the 9th century and later there was a stone residential tower, which served to protect the Kingdom of Hungary and the western border. In the late 13th century the castle became a property of Palatine Matúš Csák, who became Mr. of Váh and Tatras.
Matúš Csák of Trenčín built a tower, still known as Matthew’s, which is a dominant determinant of the whole building.
