"Skiathos’s best sundowner perch, set atop a tiny rocky island with sea on all sides and the harbor twinkling below." - Katie Silcox, Rachel Howard

Very nicely restored but almost too pristine. 5 euro for boat, 7 euro for entrance fees. Quite pretty but not as fascinating as other Greek historical site.

It’s a quick trip over with the boat transfer from the port and as you can see from land it’s relatively small. Nevertheless interesting to visit the immaculate renovated sea fortress dating back to something like 1430’ish and with a little history well presented on posters in the fortress.

Venetian fortress located on an island close to Nafplio. The boat ride from the waterfront takes about 10 minutes and costs €5 for a round trip plus castle entrance of €5. Boats runs every 30 minutes and you stay as long as you like. Great views from the castle overlooking the city are the main attraction. There are also many stone staircases and overlooks. The castle also contains a small exhibition area describing the history of the castle and a gift shop. The island also has a cute cat living in a house under a tree. Great castle to spend time on but other then views there isn’t that much to see here.

It can be visit only by boat, 4.50 euro the trip of 20 minutes. The castle can not be visited. The trip boat offeres a great view of Bourtzi Castle and of the Port of Nafplio as well.

The water castle of Bourtzi is a Venetian castle located in the middle of the harbour of Nafplio. The small island of Bourtzi in Nafplion is popular for its strong, impressive fortress. Still known by its Turkish name Bourtzi, meaning the Tower, it attracts many visitors all year round. Antonio Gambello, an architect from Bergamo, built the castle in 1471 on this tiny islet in front of the port of Nafplion, although the construction was completed by the engineer Brancaleone. The design was made specifically to fit the narrow shape of the islet. The fort's design is adjusted to the elongated shape of the islet. In its centre, there is a hexagonal three story tower where the communication between floors took place via mobile ladders for security reasons. The water supply was covered by a spacious circular reservoir situated at the basement of the tower. To the north-east a small harbour was designed to provide access to the fort; today the tourists' boats anchor here. The fort was modified and renovated but never lost its special characteristics. Bourtzi is unique, the only sea fort that exists, and the most recognizable landscape in Greece.

A beautiful venetian castle in the middle of Nafplio’s Harbour. To visit it you can go to Nafplio port. The boat will navigate around meanwhile the guide explains you it’s history.

Full castle tour from a delightful feline (whose Greek name I cannot recall). He showed us around and posed for photos. 10/10 would recommend.
