The Casa de la Moneda is a beautiful colonial courtyard house built in the middle of the 18th century used at one time as a mint.  Today, it houses part of the art collection of the Banco de la Republica including works by Bruehgel, Delacroix, Courbet and Tamayo. 

 Together with the adjacent and adjoining Museo de Botero, you will not want to miss certainly one of the most important collections of nineteenth and twentieth century art in Latin America including the works of Fernando Botero, Corot, Renoir, Bonnard, Dali, Chagall, Beckmann, Delvaux, Giacometti, Picasso, Miro, Bacon and Moore.

Both museums are as architecturally pleasing as the is the art that they contain.  The whole experience is absolutely free - they even give you a commemorative "moneda" (coin) as you exit.
