Visit
Europe´s most unconventional church, Temple Expiatori de la Sagrada
Familia, the Expiatory Temple of the Holy Family. 
The
focal point of town is La Rambla, a 1.25km (0.77mi) boulevard running
northwest and slightly uphill from Port Vell (Old Harbour) to the centre
of the city, Plaça de Catalunya. To the south of Plaça
de Catalunya you can find the old town and most of the museums and other
historical places of interest of the city. To the east of the Rambla
you can find the beautiful and romantic Barri Gòtic
The Metro
The metro is the easiest way to get around the city. Metro lines are all identified by a number and a colour; the direction is shown by the name of the line terminals. Tickets must be validated in a machine on the platform before boarding and carried at all times to avoid the Pta5000 penalty.
Buses
You may need buses or suburban trains to reach some places. Buses run along most city routes every few minutes. You can buy multiple-trip city tickets that offer worthwhile savings.
