Morro Castle is a fortification located on a hill overlooking the entrance to Havana Bay in Havana, Cuba. It was built in the late 16th century to protect the city from pirate attacks, and has served various military purposes over the centuries. Morro Castle has become an iconic symbol of Havana and is one of the city's most popular tourist attractions.

The castle is made up of several buildings, including a lighthouse, a chapel, a prison, and a museum. The museum houses exhibits on the history of Havana, including its history of pirate attacks and military conflicts. Visitors to Morro Castle can also take a tour of the castle, which provides a panoramic view of Havana and its surroundings.

Morro Castle has been the site of many important historical events over the years.
