Malta is a small but densely populated island-nation in the Mediterranean Sea. An important naval base for the many powers that ruled over Malta throughout its history, it famously resisted siege by the Ottomans in 1565. Malta is home to three UNESCO World Heritage Sites, including its fortified capital city – Valletta. Its economy is dependent on tourism, the provision of financial services, and information technology, but the Government has also been keen to encourage ventures such as film production. Malta acceded to the European Union in 2004 and to the Eurozone in 2008.
