Aglona Basilica
The largest Catholic pilgrimage site in Latvia, built 1768-1780 on a pre-Christian Latgallian worship site (settled as early as 1800-500 BC). Dominican mission founded 1699; sacred spring at Lake Egle retains healing properties recognized since 1824. The August 15 Assumption draws tens of thousands of pilgrims from Latvia, Lithuania, Poland, and Belarus. Regional classification is contested: Wikipedia assigns Aglona to Latgale, local identity is Latgalian (Aglyuna), but the 2018 law's annex does NOT include Aglona in the Sēlija parish list.

Červonka Castle
English Neo-Gothic manor built 1870 by the Plater-Zyberk family in Vecsaliena (Polish: Czerwony dwór — 'red manor' after its red brick construction). Its fairy-tale silhouette on a bend in the park makes the Polish-Lithuanian aristocratic layer of eastern Selonia immediately legible — these Catholic Polish-Lithuanian families were the confessional 'other' within the Inflanty Voivodeship, distinct from the Lutheran Courland Duchy gentry to the west.

Ilūkste
Selonia's most multiconfessional frontier town: inhabited by Selonian tribe, first mentioned 1559, with a Lutheran church (est. 1567), Catholic churches (1690, 18th century), Jesuit presence, Uniate church (1816), and Old Believer community. The St. Petersburg-Warsaw highway (1840) and Daugavpils-Tilsit railway (1873) made it a trade junction. Annual fairs in the 19th century. The town's current 'Ilūkste – our homes, our story' festival and the Sēlija rotā festival (held here in 2025) continue a tradition of communal gathering.

Subate
The most multiconfessional town in Selonia: Lutheran church, Catholic church, and Old Believer chapel (coordinates 56°0'24.8"N, 25°54'42.2"E per visitlatgale.com) stand within walking distance of each other, physically instantiating the 1561 confessional partition and its legacy. Old Believers follow the Julian calendar, meaning their Christmas and Easter fall on different dates than the Lutheran and Catholic observances — the town's festival calendar is polyrhythmic, not singular. The large Lielais Subates Lake dominates the setting.
