The Naval Museum sits at the southern end of the sea garden, on the waterfront where the park meets the port. It covers the history of the Bulgarian Navy from its founding in 1879, with displays of naval equipment, weapons, and documents spanning World War One, World War Two, and the Communist period. The collection includes submarines, torpedoes, mines, and navigation instruments, as well as a good section on the merchant marine tradition of the Black Sea coast.
The highlight, outdoors and visible from the path, is the torpedo boat Drazki — a small but historically significant vessel that in 1912 sank an Ottoman cruiser in the Black Sea. Standing beside it gives you a vivid sense of how small and vulnerable early 20th-century naval vessels actually were. The museum is well-maintained and the staff are knowledgeable; visits are most rewarding if you have some interest in naval or Balkan history.
