This large box-shaped building on Plaza de San Francisco is a former commodities market erected in 1909. In 1996 the building was completely renovated by Habaguanex and today it provides office space for foreign companies with joint ventures in Cuba. You can enter the Lonja to admire its central atrium and futuristic interior. It also houses the excellent café-restaurant El Mecurio , named after the bronze figure of the god Mercury that sits atop a dome on the roof.
