Across from the Louvre is the Tower of St. Jacques.  This Gothic tower is all that remains of the 16th-century Church of Saint-Jacques-de-la-Boucherie, “Saint James of the butchers”

Built in the early 1500’s, the tower’s opulent ornamentation reflects the wealth of the church’s patron. The butchers of Les Halles Market.
