There were originally several churches in the Nizhny Novgorod Kremlin, but today only Michael the Archangel Cathedral exists. It was built in the middle of the 16th century and rebuilt in 1628-1631. The cathedral is the tomb of Kuzma Minin. In 1828, in front of the Archangel Cathedral was constructed the obelisk in honor of Kuzma Minin and Dmitry Pozharsky (by architects Melnikov and Martos).
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.
