Iespaidīga koka celtne un izcils koka arhitektūras piemērs, kuru pamanīs katrs Plateļu apmeklētājs! Plateļu baznīca ir viens no Lietuvas vecākajiem koka dievnamiem. Pašreiz redzamais ir būvēts 1744. g., bet zvanu tornis – 1899. g. Dienvidos no baznīcas plešas Plateļu muižas parks.

The church was built in the Neoromantic style between 1936 and 1939 on the basis of a design by the architect Pavlov.  It was consecrated before the completion of construction, this happening in 1937.  The church honours the Anguished Mother of God, and the central altar is dedicated to her.  Icons in the building date back to the early 20th century, and a statue of the Fatima Mother of God is in the yard near the entrance.

In 1685, a military leader from Krakow, Belinsky, paid for the construction of a wooden church in the current location.  It was restored in 1749 and lasted until 1887, when it burned down during a storm.  A church with two steeples was designed in the Gothic style, and construction of it began one year later.  The church was consecrated in 1904 and is one of the most impressive churches in Latvia.  Attention should be paid to stained glass windows that feature images of St Meinhard and Albert.  Alongside the church is the centre of the Rēzekne-Aglona diocese, which is the seat of the local bishop.
