Boloor is known for the watch tower constructed in the era of the emperor Tipu Sultan such that now the area surrounding the squalid structure is its namesake, and buses ply at regular intervals, to and from Sultan Battery, primarily bus no.16 of the city bus system.The watch tower was constructed 15 years before his death in 1784 A.D. The place was previously known as Sultan's Battery, the word Battery meaning firing of canons. It was constructed from stones of 23 churches destroyed by Tipu Sultan, during his 15-year imprisonment of the Mangalorean Catholics and the other Christians.
