The Castle – start your visit to Olsztyn Castle by saying a wish while grabbing the nose of the Prussian Baba, a stone statue standing in the inner ward. It is said to make wishes come true. The castle, built in the14th century, was the largest fortress held by the Chapter of Warmia. In the past, the castle contained an armoury, baths, a coach house, horse stables, etc. Today it houses the Museum of Warmia and Mazury.

St James’s Church – the church was built from 1315 to 1380. It won’t be an exaggeration to say that the church has accompanied the town of Olsztyn since its earliest times. Although the exterior of the church was shaped for a few centuries, the building has well balanced proportions and a uniform style. The impressive belfry is nearly 70 meters tall. Since 1973 the church has had a function of a cathedral and in 2003 it was named a Cathedral Basilica by Pope John Paul II.

The High Gate – one of the three gatehouses to the town, also known as the Upper Gate. Over the centuries it has been used for various functions, for example an armoury and a prison. Once it gave shelter to the homeless. At present it houses a hotel.

The Old Town Hall – a former seat of the town’s authorities, today a library and a venue of many interesting art exhibitions. After the renovation works completed in 2003, the Old Town Hall regained its original shape. The oldest part of the building dates back to the 16th century.

The New Town Hall – built in 1916, it houses the Council of Olsztyn. The site was formerly occupied by the Holy Cross Church (built in the 15th century) and a graveyard.
