Lighthouses of Northern Argentina

Argentina has a lengthy coastline, extending from the warm waters of the Río de la Plata to the edge of the icy Antarctic ocean. The northern part of the coast, in Buenos Aires province, is mostly low and sandy, with dangerous shoals offshore. This coast required construction of very tall lighthouses, including several that rank with the tallest in the world. Further south, the Patagonian coast is higher and the lighthouses are shorter.

This page includes lighthouses of northern Argentina, including the northern part of Patagonia; it covers the provinces of Entre Ríos, Buenos Aires, Río Negro, and Chubut. Lighthouses farther south, in Santa Cruz Province and Tierra del Fuego, are listed on the Southern Argentina page.

Active lighthouses in Argentina are owned by the Argentine Navy and managed by the Navy's Servicio de Hidrografía Naval (SHN). The Spanish word for a lighthouse is faro; smaller lighthouses are often called balizas (beacons).

Interest in lighthouses seems to be fairly high in Argentina. In the past, there hasn't been much concern about preservation, since the great majority of the lighthouses are being maintained by the Navy. However, in recent years there has been increasing concern about the preservation of several of the country's most historic lighthouses, especially those in the far south.

ARLHS numbers are from the ARLHS World List of Lights. Admiralty numbers are from volume G of the Admiralty List of Lights & Fog Signals. U.S. NGA List numbers are from Publication 110. The official Argentine light list, Faros y Señales Marítimas, is not available online.

Entre Ríos Province Lighthouse

Río Uruguay Lighthouse
* Stella Maris (2)
1949 (station established 1908). Active; focal plane about 14 m (46 ft); red light. 12 m (40 ft) monument: the light is displayed from a post behind a statue of Stella Maris, patron saint of sailors, post and statue being atop a square cylindrical masonry tower. A good photo is available, Matias Caceres has a 2008 photo, and Google has a satellite view. This light replaced a cast iron lighthouse. Located at the end of a detached breakwater at the northern entrance to the harbor of Concepción del Uruguay, a city about 280 km (175 mi) north of Buenos Aires. Accessible only by boat. Site open, tower closed. Owner/site manager: unknown. ARLHS ARG-077.

Buenos Aires Province Lighthouses

Upper Río de la Plata Lighthouses
* Martín García (2)
1897 (station established 1884). Inactive since 1938. 13 m (42 ft) round cylindrical tower with lantern and gallery attached to a 3-story keeper's quarters/military barracks. The lighthouse was replaced by a semaphore tower in 1938; the semaphore tower still stands nearby. Alejandro Tumanoff has a photo, ARLHS also has a photo, and Forand has a 1933 photo of the light while it was active. The lighthouse is in the trees in the center of a Wikimedia photo, and trees hide it in Google's satellite view. The original lighthouse was a wood tower. Isla Martín García is located in the mouth of the Uruguay River close to the Uruguayan shore. Argentine administration of the island was disputed for many years by Uruguay; the 1973 Treaty of the Río de la Plata confirmed it in Argentine sovereignty as a nature preserve. (Previously the island had been used as a prison for out-of-power politicians.) Located near the center of the island. Tours of the island are available from Buenos Aires. Site open, tower presumably closed. Owner: Provincia de Buenos Aires. Site manager: Departamento de Áreas Protegidas. ARLHS ARG-045.
* Martín García (3)
Date unknown (station established 1938). Active; focal plane 10 m (33 ft); two yellow flashes every 10 s. 10 m (33 ft) square skeletal tower with gallery, painted yellow. Trabas has Capt. Theo Hinrich's photo, and the shadow of the light is seen in Google's satellite view. Located at the end of the island's pier. Site open, tower closed. Admiralty G0791; NGA 19292.
Piedra Diamante
Date unknown. Active; focal plane 18 m (59 ft); two long white flashes every 6 s. 18 m (59 ft) round tapered concrete tower with lantern, painted yellow. Trabas has Capt. Theo Hinrichs's photo (also seen at right). This light is close to the coast of Uruguay, but is maintained by Argentina. (A note is needed here. Under the 1973 Treaty of the Río de la Plata, this lighthouse stands in "shared waters," where Argentina and Uruguay share jurisdiction. The treaty provides that both countries may build and maintain navigational aids in shared waters. Argentina maintains navigational aids in this area, very close to the coast of Uruguay, because the shipping channel leads to Argentine ports on the Río Uruguay and Río Paraná. Uruguay owns the economic rights to the seabed under the lighthouse, and if future sedimentation should bring the shoal to the surface the resulting island would be Uruguayan territory. Because of the ambiguous geographical context, the Directory lists this lighthouse both under Uruguay and under Northern Argentina.) Located on the Barra de San Pedro, a shoal in the Río de la Plata about 8 km (5 mi) north northwest of Isla de Farallón, Uruguay. Accessible only by boat. Site open, tower closed. Admiralty G0789; NGA 19284.

1892 (Barbier, Bernard & Turenne). Active; focal plane 63 m (207 ft); one long white flash (1.4 s) every 17 s. 58 m (190 ft) triangular pyramidal "tripod" tower with central cylinder, lantern and gallery .

The light station is staffed. This is a very rare example of a French lighthouse design. The lighthouse has had an exciting life. A tornado in 1917 broke one leg of the tower, and in 1986 a fire destroyed the keeper's quarters and damaged the lighthouse. It was repaired within six months. An elevator has been installed beside the central cylinder for easy access to the light. Located about 8 km (5 mi) north of San Clemente del Tuyú on the southern cape of the Bahía Samborombón. Accessible by road; parking provided. Site open, tower closed. ARLHS ARG-011; Admiralty G0904; NGA 19420.
* Mar del Tuyú
1987. Active (privately maintained); focal plane 25 m (82 ft); quick-flashing red light. 5 m (16 ft) post mounted on the roof of a 6-story building.

Ariel Fontana's photo is at right, Javier Suden has a view from the beach, Forand has a 1950 photo, Huelse has a historic postcard view, and Google has a satellite view. A 2003 photo (no longer online) showed the lighthouse black with rust, but a 2007 photo shows it freshly repainted in red and white. Like its sibling at Cabo San Antonio, this lighthouse was prefabricated in France and assembled onsite in 1892-93. The lighthouse marks the easternmost point of Argentina, a dangerous coast noted for its shipwrecks. Although the tower is not open for climbing, there are historical displays in the base. Located off route 11 halfway between Mar de Ajó and Pinamar. Site and tower base open, tower closed. ARLHS ARG-008; Admiralty G0908; NGA 19424.

* Mar Chiquita (3)
2010 (station established 1932). Active; focal plane 21 m (69 ft); two white flashes every 15 s. 19 m (62 ft) triangular cylindrical skeletal tower. The tower also carries a slatted daymark.

It was replaced in 1932 by a light on a wood skeletal tower on the present location. The third light was a concrete skeletal tower deactivated in 2008 and demolished soon after; Maximiliano Urquiaga has a 2006 photo of the earlier light, and ARLHS has a photo dated 2009. Located just off the beach in the small seaside resort of Mar de Cobo, just south of Mar Chiquita and about 20 km (12.5 mi) north of Mar del Plata. Site open, tower closed.

Information available on lost lighthouses:

Notable faux lighthouses:

  • Iguazu, a well known observation tower and faux lighthouse, at the famous Iguazu Falls on Argentina's border with Brazil.
  • Palacio Barolo (1923), a historic office building in Buenos Aires, is crowned by a lantern containing a powerful light. As far as I know, this building has never been regarded as an aid to navigation. According to the Spanish Wikipedia article the light is lit only on special occasions. Google has a satellite view.
