Wanhua District, known in Taiwanese Hokkien as Báng-kah khu and historically as "Monga" or "Monka", is a district in Taipei, Taiwan. It is Taipei's oldest district. The district is home to historic buildings such as the Bangka Lungshan Temple, an iconic historic temple, and the Red House Theater, the first and largest teahouse and playhouse in Taiwan.

Taipei, officially Taipei City, is the capital and a special municipality of Taiwan. Located in Northern Taiwan, Taipei City is an enclave of the municipality of New Taipei City that sits about 25 km (16 mi) southwest of the northern port city of Keelung. Most of the city rests on the Taipei Basin, an ancient lakebed. The basin is bounded by the relatively narrow valleys of the Keelung and Xindian rivers, which join to form the Tamsui River along the city's western border.
