The corner of Amargura and Mercaderes is known as Cruz Verde (Green Cross) due to a green-painted cross affixed to the northwest-facing cornerstone. The cross is one of twelve that were to be found along Amargura in early colonial days, when the Vía Crucis (Way of the Cross) pilgrimage was made each Easter from Plaza de San Francisco to Plaza del Cristo.
The building—known as Casa de la Cruz Verde—has been restored, providing apartments (in a all-new top story of 21st-century design) for local people above the recently opened, and very popular, Museo del Chocolate.
