St. Casimir’s Church was founded by the Jesuits and dedicated to Lithuania’s patron saint Prince Casimir Jagiellon (1458-1484). The construction of the glorious building began in 1604 and was completed in 1635. Burnt to the ground just 20 years later when the Russians invaded in 1655, conflagration visited twice again within the next century in 1709 and 1749 before the architect, mathematician and astronomer Tomas Žebrauskas (Pol. Thomas Zubrówka, 1714-1758) restored it to more or less the form it's seen in today.
Over the centuries the church fell into the hands of the Augustinians, Napoleon’s Grande Armée, the Russian Orthodox Church (who significantly altered its appearance), the Lutherans (who used it as the garrison church for the occupying German Army during WWI) and others, including the Soviets who turned the whole place into a museum of atheism no less. Returned to the Catholic Church in 1988, the building was consecrated in 1991 and has since undergone a massive renovation project, restoring its predominantly Baroque style with Gothic and Renaissance touches. Of particular interest inside are three late Baroque altars and a recently discovered 17th-century crypt containing dark bas-reliefs featuring miscellaneous religious motifs.
References:The Broch of Gurness is an Iron Age broch village. Settlement here began sometime between 500 and 200 BC. At the centre of the settlement is a stone tower or broch, which once probably reached a height of around 10 metres. Its interior is divided into sections by upright slabs. The tower features two skins of drystone walls, with stone-floored galleries in between. These are accessed by steps. Stone ledges suggest that there was once an upper storey with a timber floor. The roof would have been thatched, surrounded by a wall walk linked by stairs to the ground floor. The broch features two hearths and a subterranean stone cistern with steps leading down into it. It is thought to have some religious significance, relating to an Iron Age cult of the underground.
The remains of the central tower are up to 3.6 metres high, and the stone walls are up to 4.1 metres thick.
