Hamilton Mausoleum was the resting place of the family of the Dukes of Hamilton. Built in the grounds of the now-demolished Hamilton Palace, its high stone used to hold the record for the longest echo within any man-made structure in the world, taking 15 seconds for the sound of a slammed door to fade. In 2014 the record was broken at the Inchindown oil storage tanks in the Scottish Highlands.
In line with his grandiose enlargement of Hamilton Palace, Alexander, 10th Duke of Hamilton, replaced his family burial vault which stood close to the east quarter of the palace in the aisle of the old and dilapidated collegiate church. Now the solitary remaining testament to the colossal scale and grandeur of the buildings which once stood in Hamilton Low Parks, Hamilton Palace Mausoleum is a Roman-style domed structure of panelled masonry. Standing to an overall height of about 37 m, it occupies a site some 200 m north of the site of Hamilton Palace. Construction was begun in 1842 by architect David Hamilton and completed by architects David Bryce and sculptor Alexander Handyside Ritchie in 1858, five years after the death of the 10th Duke.
The Duke was interred in an Egyptian sarcophagus of the Ptolemaic period, on a black marble slab in the main chapel, while 17 of his ancestors were interred in the crypt below. The coffins of the 10th Duke and his ancestors were later removed after subsidence and flooding from the River Clyde affected the mausoleum, and were re-buried in Hamilton's Bent Cemetery in 1921.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
