Stained glass windows in the Sagrada Familia interiors are a perfect example of Gaudi’s liking for color. These large and colorful stained glass windows fill the inside of the basilica with vibrant hues of green, yellow, red, and blue. To create a balance between the glass colors and the natural light, there has been a beautiful arrangement of the windows with translucent windows on the top and vibrantly colored windows at the bottom. This arrangement of the windows lights up the interiors so well that makes the vaulted ceilings stand out. If you wish to catch a spectacular glimpse of it, you can visit the attraction in the afternoon or during the sunset when the natural light peeps beautifully through these stained glass windows.

The half of the dome roofed area is known as apse in architecture. It is the place where the altar is located in the church. This structure was constructed immediately after the crypt was built in 1894. The opening in the apse with gorgeous windows fills the structure with light during the day. In the middle of the apse, you will find the raised altar that is crowned by the Latin cross with a canopy embellished with grapevines. The placement of organ pipes is just behind the altar. As far as the decoration of the apse is concerned, the interior walls are adorned with the heads and tears of the angels. The two big stone snails on both sides of the apse indicate the spiral staircase.

The Crypt of the Expiatory Temple is the most ancient part of Sagrada Familia. It is said that the crypt in La Sagrada Familia interior had been under construction much before Gaudi was appointed to design the rest of the Sagrada Familia. The style of the crypt is more of a Neo-Renaissance style with mosaic floors that depict columns abundantly embellished with roots, leaves, branches, and luscious vines. All these elements serve as a precursor to the gorgeous concepts of intrepid designs of Gaudi. The interesting fact is that the dead body of Antoni Gaudi is buried in the Crypt, and frequent masses are held every time in the crypt.

The Anagram in the Sagrada Familia Barcelona interior is a mosaic art that represents Jesus of Nazareth and his parents, the Joseph of Nazareth and the Virgin Mary. The mosaic art is located on the floor of the Temple at the center of the crossing, in front of the presidential chair, and on the Glory facade. You will discover three vertical white stripes on either side of Jesus and Joseph to symbolize Mother Mary as a queen. There is another anagram beyond the spectacular mosaics that is devoted to the Holy Family in the museum at the temple.

Another spectacular thing to see in the Sagrada Familia Barcelona interior is the Sagrada Familia Museum. It is an underground exhibition that displays drawings, construction models, liturgical furnishings, and contemporary photography by Antoni Gaudi. Several designs and plaster models of Gaudi were destroyed in a fire in 1936. However, the destroyed models were collected and restored in the Sagrada Familia Museum in the semi-basement under the Passion Facade. In today’s world, anyone can look at the exhibits and clearly state the uniqueness of Gaudi’s works. You will find these exhibitions to be a part of that latest “Inspired by Nature” section that attributes to a space of 102 square meters with 20 plaster models and large-format pictures

You will not find any Catholic church without an organ. In La Sagrada Familia interior, the organ was not at all installed until 2010, which is over 100 years after the construction of the church began. The size of the organ should be equivalent to the size of the church. Hence, around 1492 pipes were installed on two manuals and a pedalboard. It is said that more organs are required to be installed in the church as it does not provide enough sound to reach the entire part of the Sagrada Familia interiors. Therefore, you will find more organs to be placed in Sagrada Familia by 2026, which will make the attraction even more appealing.
