Built in 1880, the Former Opium House began as a warehouse for keeping opium. Macao’s heritage record places it at the head of Praça de Ponte e Horta; the government’s clinic directory lists the Tung Sin Tong Second Clinic at 273 Rua das Lorchas. The two records connect a named heritage building with the address people use today.

The Former Opium House: A Waterfront Building Given New Work
At 273 Rua das Lorchas, a former opium depot survives as a working community clinic. Its arcaded façade links a difficult commercial past to a very different public use.

A Specific Address on the Inner Harbour
From Depot to Clinic
The building served the opium depot, where the trade’s infrastructure included an opium-paste preparation workshop and monopoly bureau. After opium was banned in 1946, the house became a warehouse and then a crucible factory. An academic institution later rented it for educational purposes. The Opium House was renovated in 1996, and the Tung Sin Tong Second Clinic moved in five years later.
Reading a Working Façade
An arcade runs along the ground floor, with a covered balcony above. The sheltered passage belongs to an Inner Harbour streetscape once lined with similar buildings. Today, people approach the same frontage for the clinic. The change from opium storage to neighbourhood care is written into the building’s use, while the arches and balcony preserve the shape of its nineteenth-century commercial life.
