Olomouc lies at the heart of the Hana region, and is and always has been one of the most important cities in Moravia, where history has gone hand-in-hand with its people, science and progress. The construction of plague columns in Christian countries was instigated by the Trident Council, and at the time of its construction from 1716-1754 the Olomouc monument was one of the last examples of this fashion wave, but in its creative concept, wealth of decoration and finally its dimensions and height it differs considerably from all similar monuments. The consecration of the 35 metre-high column on 9th September 1754 was attended in person by the then first couple of the Monarchy, Empress Maria Teresa and her husband Francis I, Holy Roman Emperor, Duke of Lorraine. The Holy Trinity Column was inscribed in the UNESCO list in 2000.
This memorial column, erected in the early years of the 18th century, is the most outstanding example of a type of monument specific to central Europe. In the characteristic regional style known as ‘Olomouc Baroque’ and rising to a height of 35 m, it is decorated with many fine religious sculptures, the work of the distinguished Moravian artist Ondrej Zahner.
