The basilica was built on the site of a former wooden church that served a Dominican monastery.
The miraculous icon of the Aglona Mother of God is believed to possess healing properties and is covered by a decorative shroud for most of the year.
The structure was granted the status of a minor basilica by Pope Pius XI in 1980.
The church architecture mimics the style of the famous Basilica of St. Peter in Rome on a smaller scale.
The church is located in the Latgale region, an area historically distinct for its strong Catholic identity within predominantly Lutheran Latvia.
A holy spring located near the basilica is frequently visited by pilgrims for its purported healing water.
The basilica's exterior facade was heavily renovated in the early 21st century to preserve its original late Baroque aesthetics.
The Basilica of the Assumption of the Blessed Virgin Mary in Aglona is the most significant Roman Catholic spiritual center in Latvia. Constructed in the late Baroque style between 1768 and 1780, it is famously known for its two 60-meter-high towers. The basilica houses a miraculous 17th-century icon of the Aglona Mother of God, which is displayed above the main altar and revealed to the public only during major religious festivals. Pope John Paul II visited the site in 1993, which elevated its status to a national shrine. The complex includes an inner courtyard and is surrounded by a large park area featuring Stations of the Cross. It serves as the primary destination for the annual August 15th Assumption Day pilgrimage, drawing tens of thousands of visitors. The interior features intricate wood carvings and vaulted ceilings characteristic of 18th-century ecclesiastical architecture.
The lakeside view from the park path provides the best angle of the twin towers reflecting over the water.
Carry a water bottle to collect water from the nearby holy spring, as it is a tradition among many visitors.
Walk the outdoor Stations of the Cross path through the forest area for a more comprehensive visit beyond the main building.
If visiting in mid-August, expect significant crowds and traffic restrictions due to the national pilgrimage.
Avoid taking photographs during active mass services or using flash near the main altar icon.
Extremely crowded during the annual Assumption Day festival on August 15th; restricted access may apply during major state or church events.
Visitors should dress modestly, covering shoulders and knees; remove hats inside and maintain silence to respect those in prayer.
