The Sagrada Familia is an 1892-completed church in Barcelona that was created by Antoni Gaud. There is no set opening date for the church, which has been under construction for more than 100 years. The completion date is predicted to occur between 2036 and 2164. It is difficult to predict how long the visit will last as a result. You can schedule a whole day (8 hours), but you'll probably stay in the Sagrada Familia region for several days.

How long does a visit to this church take?

You alone are capable of measuring that period of time. The finest method to comprehend and enjoy the Sagrada Familia, in my opinion. At least twice are recommended: once during the day, when there are fewer visitors and you may enjoy some of the interior music, and once at night, when the Sagrada Familia is illuminated and has a special mood.

Eight hours –If you go very early in the morning (6 AM) or very late at night, it will take you eight hours (10 PM). Two or three days in Barcelona should be sufficient to see the Sagrada Familia.

One day – if you go to the Sagrada Familia at noon. If you do this, you’ll miss the best part of the day: the sun will shine. And there won’t be many visitors.

Three days – if you go to Sagrada Familia during all day hours, you should book your Sagrada Familia Tour in advance. Because tickets are limited and may have been reserved for a particular time. So, please make your reservation so that you get it for a specific time slot.

 If you decide to visit the Sagrada Familia, you should plan at least two or three days in Barcelona. I don’t think it’s a good idea to plan your visit on the same day as your arrival in Barcelona. You’ll need time to adapt to the city and understand how it works; you’ll want to walk around, enjoy its many places and broaden your perspective. Before jumping into a big project like any of Gaudí’s works.
