Everyone visits Sultan Mosque, but Abdul Gafoor Mosque on Hill Street showcases incredible Indo-Saracenic architecture most tourists never see. The minaret design blends Islamic and European elements uniquely in Southeast Asia.

Self-guided visits during public opening hours (Fridays 10am–noon and 3–5:30pm, other days vary). Proper dress code required - long pants, covered shoulders, shoes off. Interior geometric patterns are stunning, photography allowed outside prayer times. The building represents a fascinating architectural fusion that tells Singapore's multicultural story.
