Singapore is at the crossroads of Indian and Pacific Oceans, the Malacca, Sunda and Lombok Straits, and the South China Seas, which made it a key trading center in the India-China route. This view overlooking the Singapore River was taken from an observation point on Mount Wallich, named after Nathaniel Wallich who founded the settlement's Botanical and Experimental Garden. Today the view is no longer replicable, as Mount Wallich was levelled in 1885. Significantly, Porcher's view pre-dates one of the most well-known panoramic paintings of this viewpoint by Percy Carpenter, Singapore from Mount Wallich, 1856. Many of the same structures are visible in both the Porcher and Carpenter: Government Hill and Governor's House, the colonial residence built in 1822 by G.D. Coleman, which itself provided the colonial administration with an uninterrupted view (most view of Singapore were commissioned from this vantage point). The elevated vantage point also eliminated the unattractive mangrove swamps that dominated low-lying areas. The spires of the Armenian Church of St. Gregory the Illuminator and the Cathedral of the Good Shepherd; the broad esplanade of Telok Ayer street; the Telok Ayer market, also built after designs by Coleman, on the spit of land jutting into the basin (Pieris 43-45; Wong and Waterson 96).
