No single figure shaped Surabaya's colonial skyline more than Cosman Citroen, a Dutch architect who arrived in the booming port city in the early twentieth century and proceeded to stamp his vision across its civic landscape. The city hall, or Raadhuis, completed in 1927, stands as perhaps his finest work -- a building ambitious enough to serve as the seat of colonial municipal government and refined enough to survive as a landmark a century later. Citroen also designed the main post office, the Pos Bloc Surabaya, completed between 1917 and 1919, whose grand interior once processed the mail of an entire colonial administration. His buildings share a confident solidity, the kind of architecture that announces permanence. That Citroen died in 1935, a decade before Indonesia's independence would render his institutional commissions obsolete, adds a layer of irony the architect could not have anticipated.

The Kota Lama is not a single architectural story but a palimpsest. Dutch neoclassical and Neo-Renaissance buildings anchor the European quarter, but an Arab quarter introduces different proportions and ornamental traditions, and areas of Chinese influence add yet another layer to the streetscape. Some buildings have cycled through half a dozen identities: the Simpangsche Societeit of 1907 became the Balai Pemuda; a colonial trading office became a bank, then a political party headquarters. The Gedung Singa -- the Lion Building -- once housed a Dutch trading company designed by the celebrated architect Hendrik Petrus Berlage, the same designer behind Amsterdam's Beurs van Berlage. In Surabaya, the building's stone lions still flank the entrance, though the commerce they once guarded has long since moved on. These conversions are not losses. Each repurposing is a layer of meaning, evidence that the city metabolized its colonial inheritance rather than simply preserving or destroying it.

For many years after independence, Surabaya's relationship with its Dutch architecture was one of studied indifference. The Battle of Surabaya in November 1945 -- the fierce urban combat between Indonesian fighters and British forces that became a defining moment of the revolution -- had scarred both the city and its psyche. Colonial buildings carried associations with foreign domination, economic extraction, and the racial hierarchies of the Dutch East Indies. Maintenance budgets went elsewhere. Roofs leaked, facades crumbled, tropical vegetation colonized abandoned interiors. The neglect was not accidental; it reflected a nation's understandable desire to look forward rather than backward, to build new institutions in new buildings rather than inhabit the offices of the occupier. Some structures were demolished to make way for modern development. Others simply decayed, their fates decided by indifference rather than intention.

The turnaround began quietly and accelerated in the 2020s. City officials recognized that the Old City's architectural heritage could attract tourists and boost the local economy. In July 2024, Surabaya formally launched a revitalized Kota Lama, and within months officials reported encouraging results. What makes the revival distinctive is its tone. There is no colonial nostalgia here, no longing for the days of the Dutch East Indies. Volunteers turned out in droves to clean up the district, motivated by civic pride and aesthetic appreciation rather than historical sentimentality. Young Indonesians flock to the restored streets for the cultural experience and, frankly, for the photography -- the arched doorways and shaded colonnades make excellent backdrops. The city has threaded a difficult needle: celebrating architectural beauty while remaining clear-eyed about the system that produced it. The buildings stand as evidence that history can be preserved without being endorsed, that a wall of European brick can become fully Indonesian simply by enduring long enough.
