Andorra contains 42 Romanesque churches and chapels built between the ninth and thirteenth centuries, the highest concentration per square kilometer in Europe. Sant Joan de Caselles in Canillo parish dates to the eleventh or twelfth century and holds a Romanesque stucco altarpiece depicting the Crucifixion. The church interior maintains original Romanesque murals showing biblical scenes in pigments applied directly to stone walls. Santa Coloma Church in the southern parish is the oldest religious structure in the country, with a circular bell tower from the tenth century and a pre-Romanesque nave. Sant Esteve Church stands in Andorra la Vella's old quarter with a semicircular apse and stone construction typical of the period. Sant Martí de la Cortinada in Ordino parish preserves a complete cycle of twelfth-century wall paintings in the apse showing Christ in Majesty and the Apostles. Sant Climent de Pal near La Massana houses a Romanesque altarpiece and stone baptismal font carved from single blocks.
The Meritxell Sanctuary stands as the national shrine dedicated to Our Lady of Meritxell, patron saint of Andorra since 1873. The original Romanesque sanctuary burned completely in 1972. Architect Ricardo Bofill designed the replacement structure, completed in 1976, using concrete, stone, and slate in a modernist interpretation of Romanesque forms. The sanctuary sits in Canillo parish between Encamp and Canillo at approximately 1,500 meters elevation. A small chapel next to the main building replicates the original structure at reduced scale. September 8 marks the feast day with a pilgrimage tradition that predates written records in Andorra.
Casa de la Vall in Andorra la Vella served as the parliament building from 1702 until 2011. The structure dates to 1580 when it functioned as a private tower house for the Busquets family. In 1702 the Consell de la Terra purchased it for 1,200 Catalan pounds. The building contains the Sala del Consell where representatives from each of the seven parishes met, with a cupboard holding the Armari de les Set Claus, a seven-lock cabinet requiring all seven parish keys to open. The kitchen on the ground floor preserves the original stone hearth and wooden ceiling beams. The parliament moved to a new building in 2011 but Casa de la Vall remains open for guided tours showing the council chamber, kitchen, and small chapel.
The Madriu-Perafita-Claror Valley became a UNESCO World Heritage Cultural Landscape in 2004, covering 4,247 hectares or approximately nine percent of Andorra's total territory. The valley extends from Escaldes-Engordany parish through uninhabited high mountain terrain to the Spanish border. Stone shepherd huts called bordes and orris dot the valley floor and slopes, some structures dating to medieval transhumance practices when herders moved livestock seasonally between low and high pastures. Dry stone walls mark former field boundaries and livestock enclosures. The valley contains no roads or permanent settlements. Access requires hiking from either Escaldes-Engordany or Encamp, with the main trail starting near the Engolasters Lake and requiring four to five hours to reach the valley's upper section.
Andorra operates 181 kilometers of marked ski runs across three main resort areas. Grandvalira combines six sectors across Encamp and Canillo parishes with 128 slopes and 67 lifts, making it the largest ski area in the Pyrenees by skiable terrain. The resort spans elevations from 1,710 meters to 2,640 meters at the highest lift-served point on Tossal de la Llosada. Vallnord operates in La Massana and Ordino parishes with two connected sectors, Pal-Arinsal and Ordino-Arcalís, offering 63 kilometers of marked runs. Naturlandia in Sant Julià de Lòria provides the third ski area, smaller and oriented toward families, with access to the Rabassa forest. The ski season typically runs from December through April depending on snowfall and elevation. Summer operations convert ski lifts to transport hikers and mountain bikers to alpine trails.
Coma Pedrosa rises to 2,942 meters as Andorra's highest peak, located on the border with Spain in La Massana parish. The standard hiking route begins at the Arinsal ski area parking lot at approximately 1,500 meters elevation. The trail follows the Riu de Pla de l'Estany through pine forest before emerging above treeline into the Coma Pedrosa cirque. The final approach requires scrambling over loose rock and scree without technical climbing. Round trip distance measures approximately 13 kilometers with 1,442 meters of elevation gain. Hiking time averages six to eight hours. Snow covers the upper slopes from October through June in most years. The peak stands entirely within Coma Pedrosa Natural Park, established to protect alpine flora including gentians and edelweiss.
