The Butterworth Floating Mosque or known in Bahasa Malaysia (Malay language) as Masjid Terapung Butterworth is a jewel landmark. Located at North Butterworth Container Terminal at Bagan Luar, Butterworth, it is actually built into the sea.

Standing on stilts, it is a beautiful mosque to those who have visited. It is connected to the land by a passageway. The mosque is the second floating mosque in Penang after Masjid Jamek in Tanjung Bungah.

What is significant from afar are its slender minaret and a single dome. The dome represents the vault of heaven. The interior of the dome carries intricate geometric motifs and breathtaking patterns. On top of it, sits a crescent moon. The minaret is slim and three-leveled adjacent to the main building.

The minaret also provides a vantage point when the call to prayer or “azan” is made. “Azan” is issued five times a day which is dawn, noon, mid-afternoon, sunset and night. This mosque easily enables Muslim employees of the container terminal to perform their prayers.
