The city of Luxembourg is the capital of the namesake country, and with a population just above 100,000 it is the second smallest national capital of the European Union, after Malta's Valletta. Very different in character from the bustling metropoles of the continent, Luxembourg is defined by its mountainous location and spectacular elevations afforded by the deep and narrow valley of the rivers Alzette and Petrusse it was built upon. The city has historically been an inconquerable fortress, which led it to be nicknamed the "Gibraltar of the North".
Luxembourg may not feature on most tourists' bucket lists, but it sees a very generous share of incoming visitors every year for a city of that size. This is due to its importance in the European financial sector, with many banks and institutions having their headquarters or subsidiaries there. Moreover, as one of the founding members of the European Union, Luxembourg hosts a number of EU institutions. Finally, Luxembourg has favourable taxation regulations for international holding companies, so that many multinationals locate their European seats there. This all makes the small city have a very upscale and business feel, and the tourist industry there is geared towards the business traveller.
