Serranilla Bank is a territory of Honduras
Serranilla Bank was first shown on Spanish maps in 1510. It is administered by Colombia as part of the department of San Andrés and Providencia. Although the bank is currently occupied by Colombia, it is subject to a sovereignty dispute involving Colombia, Honduras, Nicaragua, Jamaica and the United States. Serranilla Bank is a former atoll, now a mostly submerged carbonate platform consisting of shallow reef environments. It is about 40 km in length and 32 km in width, covering an area of over 1,200 km2, almost entirely under water. Three small cays and two rocks emerge above the water to form the bank's islands. These are West Breaker, Middle Cay, East Cay, Beacon Cay and Northeast Breaker. They are largely barren, with sparse vegetation of bushes and some trees. Most of the reef is drying and many shipwrecks are located in its vicinity. [...] Honduras claims Serranilla Bank as part of its national territory in Article 10 of its Constitution. In 1986, it agreed upon a maritime boundary demarcation with Colombia that excluded Honduras of any control over the bank or its surrounding waters. The ratification of this boundary on 20 December 1999 proved to be controversial within Honduras, as it ensured that the state implicitly recognised Colombia's sovereignty over the claimed territory. Nicaragua, which has not resolved its maritime borders with Honduras or Colombia, disputed Honduras' legal right to hand over these areas before the ICJ. Despite the agreement with Colombia, however, the government has yet to officially renounce the claim in the Constitution.
