Penon de Alhucemas, together with the both Isla de Mar and Isla de Tierra are together with Ceuta, Melilla and the Rock of Penon Velez de la Gomera and the offshore island of Perejil, the last Spain areas along the Morocco Coast, and are disputed between both countries since the independence of Morocco. The three islands of Alhucemas (also written as Alhuzemas) are located 155 kilometers east of Ceuta, and about 100 kilometers west of Melilla, near the Morocco village of Sanjurjo and located about 300 meters offshore. The Alhucemas Group consists, as sayed before, of the Rock of Penon de Alhucemas, and the both western flat islets of Mar and Tierra.
Isla de Mar (35°13,0N; 03°54,0W) the northern most islet, is nothing more, than a flat, 4 meter high, rocky plate, overrunn by waters during bad weather. The only vegetation are here some kinds of moos, and some small grass.
Ilsa de Tierra (35°12,9N; 03°54,1W) is also a steep sided, 11 meter high rocky platform, on witch a runed tower is located. Tierra lies about 45 meters southwest of Isla de Mar and both islands are connected by a rock ledge over witch the waters broks all the time.
The most important islet is Penon de Alhucemas (35°12.8N; 03°53,4W) a rock, about 70 by 50 meters in area, and rising to an elevation of 27 meters in the northeastern part. The rock is completely overbuilt by a large fortification, and several groups of houses. A habour, with two piers, is situated on its east side. The two highest points on the rock, is a church from the 16the century and a watch-tower from the same time, who is used as a lighttower today.
