Ubudiah Mosque, Royal mosque in Kuala Kangsar, Malaysia

Ubudiah Mosque is a Sunni mosque on Jalan Istana at Bukit Chandan in Kuala Kangsar, built of white stone with dark Italian marble banding on its columns and arches. A large central golden onion dome rises above four minarets and turrets topped with smaller golden domes, behind a paved forecourt and low green shrubs. Its plan is octagonal, with a 20 m by 20 m main hall.

Sultan Idris Murshidul'adzam Shah commissioned the construction in 1913 following his recovery from illness. Completion was delayed until 1917 because imported marble was damaged and World War I disrupted material deliveries from Europe.

The mosque's dome and minaret count follows Perak's traditional ranks of chiefs: four pavilions, eight main towers and sixteen corner towers, echoing the Orang Besar Ampat, de-lapan and Enam Belas. It served as Perak's state mosque until 1968 and is now a royal mosque administered by a committee chaired by an appointee of the Sultan.

The mosque sits on Jalan Istana at Bukit Chandan, beside the Perak royal mausoleum (Makam Al-Ghufran) and near Istana Iskandariah. The main prayer hall measures 20 m by 20 m, ringed by a 2.5 m veranda, with an ablution pool on its east side. Non-worshippers should dress modestly and avoid the hall during congregational prayer.

The marble that two royal elephants damaged was replaced with a fresh order from Italy, but the shipment was delayed by the outbreak of World War I and arrived via South Africa. The Malay account names the elephants: the Sultan's Kulub Chandan fought Raja Chulan's Kulub Gangga for hours until Raja Chulan called his elephant off.
