How a temporary name for a flood-relief project became a provincial capital
In short: Banjarbaru was never meant to be a city. Originally a temporary designation for a planned government relocation to escape Banjarmasin's floods, the name stuck. Today, this planned city—designed with European-style parks and city halls—serves as the official capital of South Kalimantan, balancing modern urban growth with its historic diamond-mining roots.
The origins of Banjarbaru trace back to the 1950s, when frequent flooding in the provincial capital of Banjarmasin prompted a search for a new administrative center. Governor Dr. Murdjani coined the name 'Banjarbaru'—literally 'New Banjar'—as a placeholder to distinguish the site from the existing capital. While the full relocation of the provincial government remained elusive for decades, the city grew into a distinct urban entity. It was formally separated from the Banjar Regency in 1999 and finally achieved the status of provincial capital on 15 February 2022.
The city’s layout reflects a unique architectural vision. Architect D.A.W. Van der Pijl, a Dutch-descendant, designed the city based on European urban concepts, emphasizing an abundance of green space and a central city hall. This planned structure contrasts with the region's older economic activities. The Cempaka district, now part of the city, has been a hub for diamond mining since the 15th century. During the era of the Banjar Sultanate, a royal edict mandated that diamonds of four carats or larger be reserved exclusively for the sultan, highlighting the area's long-standing significance in the gemstone trade.
Modern Banjarbaru is a rapidly evolving metropolitan hub. As of mid-2025, the city’s population reached an estimated 293,332, with a demographic heavily weighted toward young adults. While the city once hosted ambitious plans for a Soviet-assisted steel industry—projects that were abandoned following the political purges of the 1960s—it has since pivoted toward a service-oriented economy. Today, the city serves as a transit and administrative node, connected by the Trans-Kalimantan Highway and the Syamsudin Noor International Airport, while maintaining its identity as the heart of the Banjarbakula metropolitan area.
