www.banrepcultural.org/museos-y-colecciones/casa-de-la-moneda; Calle 11 No 4-93; h9am-7pm Mon-Sat, 10am-5pm Sun) At the west end of the block, you’ll find this historic museum, which now houses the Colección Numismática in most of its front two floors. The exhibits (with a bit of English) start with pre-Columbian exchanges of pots and lead chronologically to misshapen coins, the introduction of a centralized bank in 1880 and how the cute tree art on the current 500 peso coin was made in the late 1990s. Behind the coins are the 10 halls of the Arte Colección, reached by overly elaborate ramps. Most of it sticks with modern splashes of oils by Colombian artists; the best, perhaps, are the giant figurative paintings by Luis Caballero (1943–95) on the 1st floor. A bit at odds with the rest are the two 1st-floor halls toward the east, focusing on 17th- and 18th-century religious objects, including two extraordinary custodias (monstrances). The largest was made of 4902g of pure gold encrusted with 1485 emeralds, one sapphire, 13 rubies, 28 diamonds, 168 amethysts, one topaz and 62 pearls. But who’s counting?
