The stained glass windows have a schedule: find out what time each color appears in the Sagrada Familia

In a Gothic cathedral, the colors are most vibrant at the top. This makes sense: the light reaches directly there, unobstructed by trees or buildings, while below, where the light is already filtered by the street, the glass becomes lighter. The Sagrada Familia does the opposite, and this is a deliberate choice by Gaudí, not a mere coincidence of the design.

Below, at eye level, are the stained-glass windows with vibrant colors, featuring the names of saints and sanctuaries written so they can be read. Above, in the tall windows, there is neither polychromy nor inscriptions: just clear glass, allowing the sunlight to illuminate the mosaic vaults and emphasize the height of the space. Gaudí himself mentioned this in conversations recorded by the architect César Martinell.

Isidre Puig Boada, an architect and disciple of Gaudí, wrote it down in 1929, three years after the master's death, in a book that would serve to document how the temple should be: the lower windows with intense colors, the upper ones with white light, and the latter with a single purpose, to illuminate the vaults.

There's a detail that's missed if you only look at the color. The white panes at the top aren't flat. They have irregular thicknesses and different textures, and that irregularity breaks down the white light into the entire spectrum it contains. Below, the color is determined by the glass. Above, it's determined by the thickness.

It's worth mentioning who created them, as they are often attributed to Gaudí with great enthusiasm. The stained glass windows in the nave were created by Joan Vila-Grau (Barcelona, 1932-2022), who began work in 1999 and worked on them for more than twenty years. Vila-Grau considered himself a painter before a stained glass artist, and he abandoned the traditional iconographic program to create what critics have called a program of color.

He also didn't use the technique that Gaudí had developed. Gaudí experimented with trichromy during the restoration of the Cathedral of Palma de Mallorca, layering primary-colored glass and then etching it with acid to achieve the precise shade. Vila-Grau, on the other hand, worked with stained glass, which fits the pieces into an H-shaped lead framework. The lead not only holds the pieces together but also defines the rhythm of the design, which is particularly noticeable in the white stained glass panels at the top, where there is no color to distract the eye.

Here's the part we haven't read anywhere else. The basilica explains that the spectacle intensifies around the two solstices, June 20th and 21st, and December 21st and 22nd, because at those times, the sun's rays strike the stained-glass windows almost perpendicularly. In the summer, the sun rises further east and enters straight through the side depicting the Nativity; in the winter, it sets earlier, before reaching the west, and enters straight through the side depicting the Passion. According to the article, at sunrise and sunset, each rose window projects its light onto the column and the vault module directly in front of it.

The problem is the time. The temple opens at 9:00 from Monday to Saturday and at 10:30 on Sundays. And in Barcelona, the sun never rises later than 8:20, not even on the latest day of the year. In other words: there isn't a single day out of the 365 in which the doors open before sunrise. On June 15th, the sun rises at 6:17, and you have to wait two hours and forty-three minutes for them to open. That low ray of the summer solstice, the one that enters perpendicularly through the blues of the Nativity scene, is seen by the pigeons.

What you can see is a low morning sun, and that depends on the month. At 9:00 AM, with the temple newly opened, the sun is 6.3 degrees above the horizon on January 15th, and 27.6 degrees on June 15th. More than four times higher. If what you're looking for is the grazing light on the blue side, the month is more important than the hour, and the month is January.

Here are two important notes to keep in mind when reading this table. The sun's altitude at 9:00 AM decreases from March to April and increases from October to November. This might seem like an error, but it's not: what changes in those two periods is the clock, not the sun. Also, the "closing time" column refers to Monday through Friday; the basilica closes at 6:00 PM every day of the year, so during spring and summer, you need to subtract two hours from the times listed.

With the other end of the day, the situation is different, and it works out well. On December 17:24, the sun sets, and the temple closes at 18:00. There's a good half hour of leeway. The winter solstice, which brings out the reds and oranges on the Passion side, is the only one of the two that can be seen from inside.

And it's not just a single day. Counting day by day throughout the entire year 2027, using the official schedule, the sunset falls within the opening hours for 122 days, distributed in a way that is not at all intuitive.

February is the month that hurts the most. On February 15th, the sun sets at 6:24 PM, and the temple closes at 6:00 PM. We're losing twenty-four minutes, and there's no way to fix it.

In October, the opposite happens, and the time change resolves the issue immediately. As we write this, on October 28, 2026, with the clocks already set back, the sun sets at 5:53 PM, and the temple closes at 7:00 PM, leaving more than an hour of daylight. On November 1st, the start of winter time, the closing time is moved up to 6:00 PM, leaving only thirteen minutes of daylight remaining. The window of opportunity doesn't disappear, but it shrinks from one day to the next.

There's a finer nuance, and it's what separates a good recommendation from an accurate one. The sun doesn't always set at the same point on the horizon. In December, it sets towards the southwest, at approximately 239 degrees of azimuth; in June, towards the northwest, at approximately 303. Only near the equinoxes does it set just to the west, at 270 degrees, which is when the light reaches the western stained-glass windows most directly.

In March, that moment is fleeting, lasting only a few minutes, and it's almost a joke. On March 17th, the sunset is at 6:59 PM, and the temple closes at 7:00 PM. The next day, it's a tie, and from that point on, the sun sets with the temple already closed, just three days before the equinox.

In September, however, it's perfect. During the last week of September, the sun sets almost exactly to the west, between 7:37 PM and 7:49 PM, and the temple is open until 8:00 PM from Monday to Friday. If you had to choose just one week of the year to see the light of the setting sun entering as directly as possible, it would be that week.

There are five rules, both regarding scheduling and regulations, all of which are publicly available, and each one has ruined someone's plans.

• On Saturdays, we close earlier, year-round, at 6:00 PM. From April to September, we close two hours earlier than on weekdays. The extended hours period we described earlier does not apply on Saturdays.
• On Sundays, it opens at 10:30 AM, not at 9:00 AM. The first hour of early morning light is not available on Sundays.
• From 9:00 AM to 10:00 AM is the "silent hour," in effect since February 2, 2026. The visit continues normally, but silence must be observed, and headphones are mandatory for any audio. This is the time of day with the lowest sun angle.
• There is no tolerance for being late. The frequently asked questions leave no room for interpretation: "The ticket is only valid for the selected time slot. If you arrive later than the indicated time, you will not be allowed access." The Park Güell, located nearby, allows a grace period of thirty minutes. The Sagrada Família, however, allows none.
• The last Sunday of October and the last Sunday of March shift the entire time zone. In October, the change in time brings the sunset back to the visiting hours from one day to the next; in March, it takes it away.

In addition to that, there is a notice on the basilica's website, on its schedule page: the management may exceptionally modify the opening hours and days when there are events taking place inside the temple. For a specific day, the valid schedule is the one displayed on the website on the day of purchase, and not the one on any other table, including this one. The complete schedules for each season are on our page for tickets, schedules, and visiting the Sagrada Família.

Regarding the price, none of this changes anything. Admission to the basilica costs 26 €, and the guided tour costs 30 €, and the price is the same at 9:00 AM as it is at 6:00 PM: lighting is not charged separately. Prices checked again on the official website on October 28, 2026. If the question is which of the four options is best, we compare them in the review of the four tickets, and if the idea is to also go up a bell tower, see which tower is worth climbing.

If you're still curious about why the building is oriented the way it is, and what other things Gaudí decided while looking at the sun, we explain it in architecture and symbolism of the Sagrada Família and in Gaudí's method.
