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:Herceg Novi was founded (on a former small fishing village, existing since Roman Empire times) as a fortress in 1382 by first Bosnian King Stjepan Tvrtko I and was called Sveti Stefan or Castelnuovo. The Turks conquered Herceg Novi in 1482, and ruled for 200 years, until 1687. However, there was a short pause between 1538 and 1539 when it was held by the Spaniards before they were defeated in the Siege of Castelnuovo. Turkey ruled again until 1687, from then until 1797, the town was ruled by the Venetian Republic.
The Herceg Novi old town is amazing. It is on a fairly steep hill that leads all the way down to the sea. Wandering through the small stairways to the various plazas and fortresses is a many hour adventure.
