The old residents of Chorio chose the safe and windless bay of the eastern coasts to live, when the danger of the pirates ceased. The residents of Chalki started building Nimborio in 1850, taking advantage of the privileges of administrative autonomy that the sultan had granted them. In 1870 the new settlement had already been flourishing due to the marine trade with the coasts of Asia Minor and the sponge fishing. It was logical that the patron saint of Nimborio was Agios Nikolaos.
It is worth visiting the homonymous church with the marvelous pebble mosaic and the tallest bell-tower in the Dodecanese and seeing the dominating Town Hall. You can stop at the Clock Tower, a building of unique architecture, the cost of which was borne by the Chalkians who live abroad, and watch the building of the post office in early Italian modernism style. Except for the public buildings, it is worth walking around the pier and the picturesque alleys of the preserved settlement. Nowhere else in the Dodecanese can you see so many mansions clustered. High-ceiling, two-storey, three-storey, neoclassic, with a view from the pediment and tiles on the roof.
