The Museo de Baler tells the history of the town and the Aurora province, with the centrepiece being the story of the Siege of Baler — the extraordinary episode in 1898 when a small Spanish garrison barricaded itself inside the Church of Saint Louis of Toulouse and held out for nearly a year after the revolution had already ended elsewhere. The museum occupies a building near the church and displays weapons, documents, and artifacts from the siege and from the broader history of the region.
The adjacent church itself is worth visiting — it is a reconstruction of the original building and contains a memorial to the siege. This is an under-visited piece of history that deserves more attention: the Baler siege is one of the stranger stories to emerge from the Spanish-American War.
