An unplanned visit to the castle turned into a real high point of our trip to Heraklion. Very reasonable to enter, €4 per adult and kids under 6 were free. Brilliant views from the top. Stay for as long or as little as you like.

A fortress build by the Venetians which is so sturdy the Ottomans took 21 years to lay spiegel and conquer it. Even then the fortress was mostly in one piece. That is also the most interesting about it. You can enter the fort/museum for 4 euro's. There is not a lot to see but there is a nice view and if you're interested in the history of Crete it's worth a visit, which will take about a 30 minutes.

Not sure I've ever seen such thick walls in a fort before, they are truly huge at this location. The place is packed with interesting Info Boards about the turbulent history of this slice of the Med. It's cheap to get in and well worth an hour of your time if you are visiting Crete.

The Koules fortress or the Venetian fortress in the old port of Heraklion dates back to the early 16th century and is very impressive. It has thick walls and you walk through grand doors to a number of interesting rooms. There are cannons, cannonballs, things from shipwrecks such as ancient amphorae and more. The views from the top are beautiful.

This was a return trip for us to the impressive Fortress of Koules which dominates the entrance to the Venetian harbour of Heraklion. Easy to recommend a visit and such good value at only 4 euro per adult ticket. Some great views across the harbour from the roof of the fortress and some interesting items on display along with historical information that is nicely presented.

Great value - only 8 Euros for 2 adults and a child - and not crowded. A truly impressive structure in a striking location, completely atmospheric. We enjoyed a good hour or so walking around and up to the battlements. The information boards have a good sense of the fortresses' history, and it is one of those attractions that everyone can enjoy.

There's an amazing atmosphere within the fortress, you should immerse yourself in the fortress and imagine all the action that happened, all the ideas and emotions that occurred within walls of fortress during attacks. Beside that there are couple canons, canon balls, artifacts, detailed description providing historical facts and nice views from 2nd floor. Entrance is only 4 euros. After taking look in fortress you should take walk all the way to light house

Loved visiting fort, located on the waterfront not a massive fort so you don't need long to visit, many of the rooms are set up more as a museum that way fort was set up centuries ago. Best thing about fort is the views from the walls, you can walk around the walls and get great views of the ocean, promenade and city area. Very reasonable price for entry so for me a must do while in Heraklion.

We enjoyed walking to the Venetian Fortress along the harbor and touring it in the afternoon. It has a 4 Euro entrance fee (reasonable) and is a great sight to visit for the history and the views. The first floor is set up with panels detailing the history in Greek & English. Then the upper part of fortress offers views of the water, harbor, city of Heraklion and mountains in the distance. It is an interesting historical sight with wonderful views and is recommended to those visiting Heraklion. I'm really glad we toured it.

Nice to see from distance and close up, but unfortunately not open at time of my visit. Could walk the long causeway to the end. Bit I personally opted out,just looking from side of fort.
