In the very heart of Kangar stands the elegant Alwi Mosque—a true architectural gem and a symbol of the state of Perlis. This historic building, constructed in 1933, is a rare example of Mughal architecture in the region. The mosque owes its name to Raja Syed Alwi, who formally opened it, establishing its status as a major religious center in Malaysia for many years.

The main visual feature of the structure is its magnificent onion dome, crowning an octagonal drum. The building harmoniously combines features of colonial heritage and Eastern classics: arched windows, exquisite balustrades, and two towers resembling obelisks create a unique appearance that makes the mosque stand out against the backdrop of modern urban buildings. In 1988, this site was officially recognized as a national heritage of Malaysia.
Even though there are now larger, more modern temples in the state, Masjid Alwi (as it is called by locals) remains one of the oldest and most revered mosques. It attracts tourists not only with its history but also with a special atmosphere of tranquility that has been preserved within its walls for nearly a century.
