Tengku Tengah Zaharah Mosque or Floating Mosque was named after the mother of the late Sultan of Terengganu Sultan Mahmud Al-Muktafi Billah Shah , namely the late Tengku Intan Zaharah binti Almarhum Tengku Setia DiRaja Tengku Omar. The mosque is located 4 km from Kuala Terengganu city center . This mosque has its own beauty and uniqueness compared to other mosques that have been built. This mosque is built on the water at the mouth of the Ibai River which makes it the premier floating mosque in Malaysia.

The mosque combines modern and Moorish architecture; incorporating the use of marble, ceramics, mosaic works and bomanite paving. The white structure of the mosque covers an area of roughly 5 acres and can accommodate up to 2000 attendees at a time. The mosque is linked via two bridges from the north and south sides of the public car park. The pristine white edifice of the mosque accommodates several facilities in its two- storeyed building, including the main prayer hall, female prayer gallery, royal lounge, mini library, Imam’s room, office, ablution areas and toilet facilities. Sheathed in off-white coating, a grand bulbous dome sits on the upper tier of the main building. Its hexagon-shaped base is made of stained glass windows, with smaller clerestory windows punctured through the dome’s sides. Similar shaped domes in a smaller scale are located on the lower tiers across the mosque, marking the entrance porches and covered pavilions. On the Northeast side, a towering Mamluk-inspired minaret stands with Moorish- influenced horseshoe arches seen in the opening of each of its four tiers.

Many such traditional Middle-Eastern inspired design elements are embedded on the building elevation with an array of arches used as window openings and at the courtyard area. At the building facade, several projected bay-like windows are incorporated into the mosque facade. Smaller fenestrations are also arranged accordingly. Projected turrets which stand on its corner walls are used to cover the pavilions overlooking the river. The main prayer hall is sheathed in a white colour tone, formed by main columns flanking the hexagonal void under the main dome. The four front columns are decorated with attached panels, similar to mashrabiya wall panels. The qibla front wall is earmarked with a vaulted mihrab niche, with an intricate timber minbar platform located in the middle.
