Opened in 1992 on the 500th anniversary of Columbus' discovery of the New World, the Naval Museum occupies a great colonial building, which was once a Jesuit college. It features, for the most part, a grand collection of reconstructed cityscapes and boat models from throughout the centuries, but woefully lacks much in the way of actual artifacts (although there are some nice torpedoes). It can be a little boring unless you're a naval history fanatic. Tours in English (COP$25,000) are available for the latter.
