Masjid Ubudiah is Perak's royal mosque, and is located in the royal town of Kuala Kangsar, Malaysia. It is often regarded as Malaysia's most beautiful mosque. The mosque was designed by Arthur Benison Hubback, a government architect who is notably credited for the design of the Ipoh railway station and the Kuala Lumpur railway station. Construction began in 1910 but it was abandoned during World War I. It was also delayed when the then crown prince's elephant walked over and cracked the imported Italian marble floor. The mosque was finally completed in 1919.
