Basilica de Santa Maria del Pi (Basilica of St. Mary of the Pine), Barcelona

This remarkable early Catalan Gothic church stands as one of the most fortress-like structures you'll encounter. It exudes a sense of grandeur with its imposing, dark, and massive presence, punctuated only by the main entrance and the huge rose window, reputedly the largest in the world. To witness the window's vibrant colors at their best, try to view it from inside during the late afternoon.

The church derived its name from the solitary pi (pine tree) that once stood in the marshy lowland beyond the 4th-century Roman walls. A previous church from the 10th century preceded the current one, which commenced construction in 1322 and was ultimately consecrated in 1453.

Upon entering, two interesting features await: the original wooden choir loft and the painting "La Mare de Deu dels Desamparats" ("Our Lady of the Helpless") by Ramón Amadeu. It is said that the artist used his wife and children as models for the Virgin and children in the painting. The church frequently hosts classical guitar concerts by renowned soloists. Guided tours of the basilica and bell tower are available in English, with prior reservation.

Why You Should Visit:
Very nice in its simplicity; a peaceful place to sit quietly and cool off while marveling at the world's largest stained glass rose window.

Tip:
If you visit early or late, admission to the church is free (otherwise, there is a nominal fee). For a few extra euros, you can ascend the bell tower and enjoy a panoramic 360-degree view of the city. However, do take note of the timing, as the tower closes after dusk.
