Castillo de San Cristobal

Small free museum under the Plaza De España. The entrance is small and look like is under construction but its actually open to the public. The staff is very friendly and informative.

Fantastic to see how they have recovered the castle from being buried. It's great to read about a piece of British history from the "other side". El Tiger; the cannon that took Nelson's arm is a great little secret.

Located only underground and hard to find, yet housing a famous canon that faced against Nelson's force. Lacking English descriptions and some more history context (there was a handout in English but also quite vague). A bit of lost potential.

In fact, it is not a castle at all, but just a story about a castle that once existed here. All that can be seen are some fragments of walls made of massive stone blocks, a refurbished cannon and a few rusty cannons. Plus written information, on some panels, on the reinforced concrete walls. Nothing impressive, maybe just the age of the place. Entry is free.

Ruins are conserved very well under the road of city centre, it is a small piece of history good to know for everyone.

Interesting small, and free, museum regarding the English attack on the island of Tenerife. It also features the canon that injured Lord Nelson. There is information available in multiple languages.

Definitely worth spending 15 minutes having a look round at the remains of the fort, very interesting history

The Castle of San Cristóbal was the first fortification system on the island. What is left are underground foundations. The famous El Tigre cannon was installed in a dedicated room at the centre. Apparently, El Tigre is the cannon that injured Nelson during the Battle of Santa Cruz de Tenerife (1797).
