Barcelona claims to have been the entry port of chocolate into Europe, based on the arrival of a 1520 shipment of cacao from Mexico. A Cistercian monk in the New World sent it to the Monasterio de Piedra in Aragón complete with a recipe for a chocolate drink. This little museum is full of historical and quasi-historical tidbits, but it’s really designed to make you crave chocolate. The first thing you see is a chocolate fountain, and even your ticket is a chocolate bar. Some of the chocolate sculptures are truly amazing—a Komodo dragon, a bullfight, soccer players, the Barcelona Zoo’s late and lamented albino gorilla (in white chocolate), and even a tableau of Sancho Panza and Don Quijote.
