About Luxembourg
Luxembourg Airport (LUX) is one of Europe's smaller national gateways but serves the world's richest country per capita with a focused network of European connections. Luxair and Ryanair cover the main routes; the airport is 6 km from Luxembourg City centre, connected by bus in 20 minutes. Luxembourg City itself is a UNESCO World Heritage Site — the Bock Casemates, a 23-kilometre network of underground rock-hewn tunnels and chambers, run beneath the city's old fortifications, while the Corniche promenade above gives one of Europe's most dramatic old town views over the Petrusse and Alzette valleys. The Grand Duchy's position at the heart of the EU quarter — the Court of Justice, Court of Auditors, and European Investment Bank are all based here — gives the city an international character disproportionate to its size. Moselle Valley wine country, the Mullerthal hiking region ('Little Switzerland'), and the Ardennes forest are all within 45 minutes by road.
