Long before it had a tallest tower, this stretch of riverbank was five separate hamlets recorded by 19th-century chroniclers — and much of its modern shape was set not by planners, but by a Cold War-era refugee wave.
Scholar-official Trịnh Hoài Đức records five hamlets on this stretch of riverbank in his Gia Định Thành Thông Chí — Bình Hòa, Bình Lợi Trung, Thạnh Đa, Phú Mỹ and Bình Quới Tây — all part of Bình Trị canton, Gia Định province.
French engineers cut a short canal through Thạnh Đa hamlet to shorten a river bend by 12 km. The unintended side effect: the peninsula becomes an island, cut off from the mainland — see Places to discover below.
Gia Định province is split into four districts. The area is folded into Gò Vấp district, administered from the old French provincial hall — still standing today as the district's seat of government.
After the Geneva Accords split the country, a large wave of Catholic refugees from North Vietnam settles in the Bình Hòa – Thạnh Mỹ Tây area, following President Ngô Đình Diệm's resettlement drive. Their parish churches still anchor several neighborhoods.
Bình Hòa and Thạnh Mỹ Tây, until then communes of Gò Vấp district, are briefly elevated to separate districts, then merged on 20 May 1976 into a single new district: Bình Thạnh.
Population reaches roughly 552,000 across 20.8 km² — a dense, mostly residential district squeezed between the Sài Gòn River and the city center.
A citywide ward reform dissolves the district structure, but its new wards are named Gia Định, Bình Hòa, Thạnh Mỹ Tây and Bình Quới — reviving, almost word for word, the historic place names the area has carried since the 19th century.
