Krustpils Castle
Built 1255-1297 by the Archbishop of Riga, granted to General Nikolai von Korff by Stephen Báthory in 1585, owned by the Korff family until the 1920 agrarian reform. The castle's ownership history mirrors Selonia's political transitions: Livonian Order (1359), Polish-Lithuanian Commonwealth (1561-1772), Russian Empire, Latvian Republic, Soviet military (1944-1991), and since 1994 the Jēkabpils Museum of History. Baroque elements were added to the medieval structure in the 18th century.

Pļaviņas Hydroelectric Dam
Constructed 1961-1965, the dam submerged the sacred Staburags cliff, villages, graves, and a complete cultural ecology of the Daugava gorge. The 1958 protests against the dam were among the first acts of civil society resistance in Soviet Latvia. The dam generates one quarter of Latvia's electricity, but people remain divided about its cost. The Dieva auss memorial (2003) and the annual Opening of the Selonia Tourism Season at nearby Vīgante Park maintain the cultural memory of what was lost.

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.
