This distinctive, slate-blue building was built in 1838 for the wealthy del Junco family and since 1980 has housed a collection of artifacts, photographs, memorabilia and tools—some of them gruesome—chronicling the sugar and slave industries, on which the city's wealth was built. 

Located in the outskirts of the city of Matanzas, The Yumurí valley offers one of the most spellbinding views in Cuba. The best perspective of the Valley can be seen from the viewpoint at the Bacunayagua Bridge from where the splendor of the valley can be fully appreciated. There are ecotourism trails in the valley.

This beautifully restored museum is worth a visit for its wide-ranging exhibits on everything from archeology to ethnology to numismatics to colonial weaponry. The museum has a beautiful, bright inner courtyard displaying some lovely, early 19th-century furniture, as well as an ornate horse-drawn hearse. Lots of natural light illuminates the quirky, Victorian-era potpourri of natural-history exhibits, from bugs, butterflies, polymitas (snails with multicolored shells), to preserved fleas in nuptial dress, viewed under a magnifying glass. Antique buttons and buckles, pen nibs, death masks, a Masonic lodge throne in the shape of a peacock. On the historical side, there are the usual photographs of Cárdenas heroes of the wars of independence and the Revolution and a gruesome reminder of the risks rebels took, in the form of the garrote used to strangle victims to death. 

Recently restored on the outside, this massive, neoclassical church with two ornate towers is famous for its interior frescoes. In front of the church, there is a huge ceiba tree with a heavy, metal bell hanging from one of the branches, commemorating the bells that were rung to call in slaves from the sugar plantations. On the ground below lies a large, antique metal gear from a sugar mill.
