The fortified enclosure of the Venetian Chandakas of the 15th century, which is still preserved today, is one of the most significant monuments of its kind in the whole Mediterranean basin.
Triangular in shape, with its base at the sea, the mighty enceinte has a perimeter of about 5.5 kilometres. The hallmark of the defensive layout are the bastions, linked by curtain walls decorated at many points by escutcheons and the lion of St. Mark, symbol of Venetian omnipotence. The gates in the enceinte, which served to link the town to the countryside, still stand as important architectural monuments.
To this day, the walls that withstood the Ottoman siege in the mid-17th century mark out the boundary of the old town.

The island of Spinalonga (Gr: Σπιναλόγκα), officially known as Kalydon (Καλυδών), is located in the Gulf of Elounda in north-eastern Crete, in Lasithi prefecture, next to the town of Elounda. The official Greek name of the island today is Kalydon. Originally, Spinalonga was not an island, it was part of the island of Crete. During Venetian occupation the island was carved out of the coast for defense purposes and a fort was built there. A popular name for the island since Venetian rule is Spinalonga. During Venetian rule, salt was harvested from salt pans around the island. The island has also been used as a leper colony. Spinalonga has appeared in novels, television series, and a short film.

The Natural History Museum of Crete is housed in the renovated former premises of the Heraklion Public Power Corporation, on Dermatas’ Bay.

The Archaeological Museum of Aghios Nikolaos is one of the most important in Crete and has been in operation since 1969. It houses collections of very important archaeological finds from the whole of Eastern Crete, an area extending from Malia as far as Zakros. These are displayed in chronological order from the Neolithic period (5700 - 2800 B.C.) to the end of the Roman times (100 B.C. - 400 A.D.) Its showcases include more than 1350 vases from the 3rd millennium B.C. as well as gold and copper finds (the most ancient found in Crete).

Lake Voulismeni (Gr: Λίμνη Βουλισμένη) or just "the Lake" for the locals, is located at the centre of the town of Agios Nikolaos. It has a circular shape of a diameter of 137 m and depth 64 m. The lake connects to the harbour of the town by a channel dug in 1870.
A panoramic view of the lake can be seen from a small park situated above it. According to legend, the goddess Athena bathed in it. Every year at midnight turning to Orthodox Christian Easter day, the majority of the population of the town gathers around the lake to celebrate with fireworks, and firecrackers.
It was reported that the German army during their withdrawal from the area at WW2, disposed parts of their weaponry and/or vehicles into the deep lake.
A local urban legend has it that the lake is bottomless. That notion is potentially based on its impressively disproportional high depth compared to its width (64m depth on only 134m width) or/and on locals noticing disturbances at the surface or also the level of the water during the Santorini (Thera) earthquake of 1956. Because of the latter, many assume a possible geological relation of the two locations, but this claim has not been substantiated by known scientific surveys to date.

Agios Nikólaos (GR: Αγιος Νικόλαος), with 9.500 inhabitants, is the capital of the Lassithi province of Crete.

A monument of natural beauty that attract a lot of local and foreign visitors. The gorge of Sarakina (GR: Σαρακίνα) is one of the most beautiful in Crete. Its steep, vertical walls in some parts reach a height up to 250 m. Its widest opening is no more than 15 metres while in some places it’s so narrow that its sides seem to join each other. Its rich flora and fauna, the dittany, the wild birds that nest there, the running water make the route through the gorge a worthwhile experience.
