This monument, the focal point of Dolní nám?stí, was built in baroque style after the plague swept through Olomouc in 1713-15. The lower part of the statue shows eight patron saints against plagues, while the upper part is dedicated to the Virgin Mary.
The town's pride and joy is this 35m-high (115ft) baroque sculpture that dominates the square and is a popular meeting spot for local residents. The trinity column was built between 1716 and 1754 and is allegedly the biggest single baroque sculpture in Central Europe. In 2000 the column was awarded an inscription on Unesco's World Heritage list. The individual statues depict a bewildering array of Catholic religious motifs, including the Holy Trinity, the Twelve apostles, the assumption of Mary, and some of the best-known saints. There's a small chapel at the base of the column that’s sometimes open during the day for you to poke your nose in.
Olomouc is all about centuries-old history, but this more recent relic of the Cold War is also worth exploring on a guided tour. The shelter was built between 1953 and 1956 and was designed to shelter a lucky few from the ravages of a chemical or nuclear strike. Tours are arranged by and begin at the Olomouc Information Centre.
