Strasbourg, in eastern France, is the official seat of the European Parliament and many other European institutions, such as the Council of Europe and the European Ombudsman. However, Strasbourg is much more than that. In 1988, the historic city centre became a UNESCO World Heritage Site, and rightly so! It is located on the Grande Île, an island in the Ill River. The most beautiful of the bridges leading to the island are the Ponts Couverts, a set of three bridges and four towers dating back to the 13th century. The centre itself is dominated by Strasbourg Cathedral, which is the sixth-tallest church in the world and constitutes a stunning example of Gothic architecture.
