As Lisbon grew in the mid-20th century, it expanded north, away from the river. Residential and business districts were born around long, broad avenues, today collectively known as Avenidas Novas ("New Avenues"). Originally many palatial mansions lined these avenues. Most who visit Lisbon will go through it to reach some of the city's best museums (the Gulbenkian is not to be missed), and many will also be making it their home, as a large number of the city's hotels are located here. In between it all there are some excellent restaurants to look for, as well as the city's most popular shopping malls. Areas very well served by transports, services, commerce, schools and only five minutes from the Lisbon airport, and good accesses to the main roads, leading to all points of the city or to exit Lisbon North/South.
