Banica Dominican Republic Pillar Dial 350
A small pillar dial with a vertical dial on one face. The dial markings sit below a triangular crown inscribed with the date MDCCVC, showing 1795 as the year it was carved. Today, the bottom portion of the pillar appears to be reconstructed and the gnomon is missing.
Los Rios Santo Domingo Distrito Nacional Dominican Republic Compound Dial 903
This highly decorated monument sundial is composed of three sundials (Horizontal, Polar and Equatorial) with a common gnomon. All of the dials are built mainly of limestone. The large polar dial (wings), small horizontal dial (tail) and gnomon (body) recreate a “hummingbird”, the universal symbol for diabetes. (The hospital specializing in diabetes is only 500m away). The dials are delineated in half hours and have a variety of graphics on all three dials. In the same location, albeit separated there is another equatorial clock that is five times smaller and has a custom gnomon in the shape of the "little hummingbird”; this sundial is mounted on top of a column and has been adjusted to the local solar time. Nearby is a plaque with the equation of time.
Santo Domingo Dominican Republic Pillar Dial 348
At the upper end of a tapering pillar is a rock cube with vertical dials on two faces. The dial was erected during the administration of Francisco Rubio y Pernaranda around 1753 in front of the Governor's Palace and was used during the centuries of Spanish rule as the official marker of time. An equatorial dial was placed on top of the cube probably around 1787 and was later broken off by a hurricane. In 1992, as part of the Fifth Centennial Discovery activities, the equatorial dial was reinstalled on top. Dial sits atop a mortar or rock block.
