There were several major lighthouses built by the Spaniards when the U.S. took over Puerto Rico in 1898 after the Spanish American War. The faro (Spanish for lighthouse) El Morro was damaged in the war and was redesigned & rebuilt on its original foundation on Morro Castle.
Point Borinquen Lighthouse: This lighthouse is on the Coast Guard Base at Aquadilla. The keepers house is two apartments, and is rented out for vacation quarters for military people. This lighthouse was built after the first Point Borinquen Lighthouse was demolished by a tsunami in 1918.
Morrillo's Lighthouse: is on top of a rocky mountain known as "Punta Morrillo" in Arecibo, which is located on the north coast of of the island, 49 miles West of San Juan. This was the last lighthouse built by the Spanish government in 1898. The style of construction is neo-classical and the attached hexagonal tower is covered by a bronze dome with a working lantern. The original lens was a third-order Fresnel, with an 18 mile radius. At the present time it has a 190mm lens with a white flash every 5 seconds.
In the interior of the lighthouse, you will be able to observe artifacts found at the bottom of the ocean, a 1910 diving suit, a replica of the US Constitution and on its wall literature relating to the history of the Arecibo Lighthouse and the Spanish-American War.
Los Morrillos Lighthouse: is one of the most popular and scenic places to see in Puerto Rico. Among all the places to visit in Cabo Rojo, this is by far the most impressive site. Feast your eyes on the magnificent architecture of the lighthouse, the high and muscular cliffs that serve as a pedestal to the lighthouse and the beautiful vistas of blue turquoise waters and a quiet soft white sand cove for beach lovers. Los Morrillos Lighthouse was built in 1882 by the Spanish. The limestone cliffs drop off some 200 feet into the water. The cliffs are quite breathtaking but very dangerous.
Los Morrillos is a great area for hiking and bicycling. As you walk towards the lighthouse you will see a path on the right with awesome ocean vistas of the blue horizon. Keep on walking down the hill if you are adventurous and you will find stunning natural limestone rock formations of peaks and natural arches. As you walk the path around the lighthouse you will discover many natural bridges and caves along the limestone cliffs.
Faro de las Cabezas de San Juan: is located on the northeastern part of the highest point of Cape San Juan in Fajardo, Puerto Rico. The Spanish erected the lighthouse, officially lit on May 2, 1882. Inside, facing the main entrance, a corridor leads to an eight-step stairway ascending into the lighthouse tower. An elaborate, richly decorated cast-iron stairway leads to the stone central lantern. The original illuminating apparatus, not changed until after 1898, had an 18-mile range and displayed a fixed white light which every three minutes flashed red. This neo-classic structure appears castle-like with the parapet in the portico's roof and with the tower's rectangular cornice in the middle section. The lighthouse is located within the Las Cabezas de San Juan Nature Reserve, and is managed by the Conservation Trust of Puerto Rico.
The Culebrita Lighthouse: was built by the Spanish Crown between 1882 - 1886. The main reason for construction was to ascertain sovereignty over Culebra and its surrounding islands between the British and Danish. The U.S. Navy used it as an observation post until 1975. Since then the lighthouse has been subject to the harsh environment with very little thought of providing maintenance. On October 22, 1981, the Culebrita Lighthouse was dedicated a historical monument of the United States. However, the Fish and Wildlife Service, who currently owns the Island of Culebra, has not done much to preserve the lighthouse.
Punta Higuero Lighthouse: Located in Rincon, which is on the northwest corner of the island about 93 miles from San Juan. Still in use, this lighthouse also serves as a popular tourist attraction. It was first built in the early 1890's by the Spaniards; however, it suffered severe damage in an earthquake in 1921. It has since been rebuilt and it's 26,000 candlepower rotating beacon regularly warns ships of impending disaster.
Guanica Lighthouse: was built in 1893 and once held a sixth-order Fresnel lens that showed a white light visible 8 miles away. Guanica, the location of the lighthouse, is where the invasion by the U.S. took place in 1898, during the Spanish-American War. In 1950 the historic lighthouse was decomissioned and the Fresnel lens removed. The active light is now on a 40' steel tower known as Guanica Rear Range Light. The old structure is in ruins now but there has been some interest in restoration.
Caja de Muerto Lighthouse: is a 19th century building which has been restored by the Department of Natural Resources. It sits virtually alone on the island of Caja de Muertos (Coffin Island) and now houses a lookout and a museum. A trip to the island would just not be complete without a visit to this old building where you not only have an amazing view, but you can learn a little about the islands history as well.
El Morro Lighthouse: Visitors to Puerto Rico today, whether arriving by air or on a cruise ship, have an excellent view of the Castillo de San Felipe del Morro, a fortress that has protected San Juan harbor since the mid-16th Century. Puerto Rico’s first lighthouse was erected atop this fort in 1843. It was replaced by a second tower in 1876; this was itself heavily damaged during the Spanish-American War.
In 1908 the U.S. Navy built the present Moorish style lighthouse on the foundation of the 1876 lighthouse. The square tower has a third-order Fresnel lens with a focal plane of 181’ above the water. The light flashes at 10 second intervals with every fourth flash blocked. The fortress was handed over to the National Park Service in 1961 to be preserved as a museum. In 1983, it was declared a ‘World Heritage Site’ by the United Nations. Although, the fortress and surrounding grounds are open to the public, the lighthouse is not.
Manuabo Lighthouse: The little town of Maunabo is located 51 miles southeast of San Juan. The town is flanked by the last two legs of the Cordillera Central. One of its best known attractions is this lighthouse located in an area called Punta Tuna. The lighthouse is still in operation. It was built by the Spaniards in the late 19th century, shortly before Puerto Rico was turned over to the United States as spoils of the Spanish-American War.
Although its antique fresnel lens has been supplanted by modern technology, the Punta Tuna lighthouse still warns ships of the risks of sailing too close to Maunabo's shores. It is the only lighthouse of a dozen or so on the island manned by U.S. Coast Guard personnel.
Punta Figura Lighthouse: Located in the town of Arroyo, this structure was built in 1893. The lighthouse had been a victum of negligence in the past, but as you can see it has since been beautifully restored.
