(click to enlarge) The Iglesia de San Jose near Casco Viejo has a deservedly famous, spectacular gold altar.
(click to enlarge) I'm not sure which church this and the next picture are from. (I'm not a good record-keeper.) Might be the Iglesia de la Merced a block or so away from the Iglesia de San Jose and the Cathedral. In any case, the light and colors are nice.
