Nice city to visit!!! It is a fortified village that protected Pisa for a long time...
Lucca is filled with great architecture and is really nearby Pisa. In this area, you may wanna see the famous leaning "Pisa Tower
" and its whole-marble Baptistery.
If you can, try to go to Florence (Firenze) or Sienna or even visit the whole Toscana
As a voyager, I really enjoyed visiting Toscana.
Have fun there! I know famous music artists such as MUSE or other rock bands already performed live at this exact same location
