The fortress and the museum are not the same historical institution. San Severino began as a military structure; its use as a museum belongs to a later project of interpretation and remembrance. A stone wall may be historic, while a label, sculpture or exhibition arrangement is a modern way of explaining that history. Both deserve attention, but they answer different questions.
The museum is also not a generic display of an undifferentiated African heritage. Matanzas has distinct religious, musical and community traditions. Institutional descriptions connect the center with African-descended groups, but a reference to collaboration does not mean visitors are entitled to attend every gathering or ritual. Respect the boundary between interpretation offered publicly and knowledge or practice that participants choose to keep within their communities.
