La Sagrada Familia is an expiatory church meaning that its construction is funded strictly by donations and now from tour revenue. When completed it will be open for public use and is currently used for special occasions and holidays.
For my own personal experience, the great expanses of the interior are remarkable and the views from the towers are incredible. It is insane how much detail is on every surface of this place and the stained glass in the windows creates a beautiful prismatic affect. The columns inside are reminiscent of trees and the hyperbolic domes of the ceiling look like the canopy of foliage atop the tree trunks. It's almost impossible to write about the experience of walking through this place, you have to do it yourself! I cannot wait until its completed and we can go and see the transformation in person!

Notes: *Definitely buy your tickets ahead of time as lines can get very
long. Tickets are for timed entry, so get there about 10 minutes
before the time on your tickets and you get to skip the lines.
*There are two towers to choose from. Either is fine as long as you
go up in one. The Passion Façade is 75m and the Nativity Façade
is 55m. We chose the taller of the two.
*We suggest doing the Basilica+Audio-Guide+Towers. The
entrance to the tower is the timed entry part of the ticket. We
suggest planning to tour the tower first so that you can then take
your time exploring the rest of the church without rushing to
make it to the tower.
