Gibraltar is a British overseas territory on the southern tip of the Iberian Peninsula in southern Europe. It has been under the sovereignty of the British Kingdom since 1704, but has since been claimed by Spain. Geographically it is located on the “Strait of Gibraltar” with the narrowest point between Europe and Africa.

You can reach Gibraltar by plane to the Spanish city of Malaga and then by bus about 1.5 hours to La Linea de la Conception. From there you can easily and comfortably walk across the border. Various scheduled flights are available directly to Gibraltar only from Great Britain.

Only around 34,000 people live in Gibraltar on 6.5 km2 and the local currency is the Gibraltar pound, which is nevertheless convertible 1:1 with the British pound sterling. The Schengen visa law does not apply there, and no other EU regulations apply there either, but entry is still unproblematic. The official language is mainly English.

The Rock of Gibraltar is certainly the city's most famous landmark and offers several viewing points at different levels. This huge limestone rock catches the eye from a long distance. The rock is teeming with countless Barbary macaques, which are always a popular photo opportunity for tourists. With normal visibility it is relatively easy to see all the way to African Morocco from the rock.

Gibraltar is mainly driven by tourism. The climate there is warm all year round and is ideal for beach tourists. Other attractions include two caves, St. Michael's Cave and Gorham Cave. Both caves and the associated tunnels used to serve as military defense fortifications; some of them were carved into the rock. The Gibraltar Cathedral and Europa Point with the Gibraltar Lighthouse are also among the most important excursion destinations. In the 1990s, one of the largest mosques in a non-Islamic country was built in Gibraltar, the Ibrahim al Ibrahim Mosque. Ultimately, there are still 4 Orthodox synagogues here, which are also worth a visit.

In July 2013 I visited Gibraltar for the only time so far. I chose the entry option via Spain and spent two great days in the small city-state. Gibraltar looks absolutely British with its architecture and many pubs. I was very surprised at how crowded the city was in summer and how comfortable it is to stay there. After a short tour of the Rock of Gibraltar with its world-famous monkeys and a quick visit to the two caves, my stay took place mainly in the city center. What is also very interesting is the fact that there is a normal road over the airport runway. Vehicles and people simply wait at a barrier for arriving and departing aircraft. This process is very interesting to watch and unique in the world.
