Tsuruga-jō Castle.

Distinctive for its striking red-tiled roof—a rare feature among Japanese fortresses—Tsuruga-jō Castle stands as a symbol of samurai resilience. Though the original 14th-century structure was destroyed after standing as a final stronghold during the 1868 Boshin War, the 1960s concrete reconstruction faithfully honors its heritage, with its signature Edo-period red tiles restored in 2011. Inside, a museum showcases samurai armor, swords, and local history, leading to a top-floor lookout with views of Aizuwakamatsu. The surrounding park, framed by original stone walls and moats, comes alive with cherry blossoms in spring. For a quieter moment, visitors can stop by the reconstructed Rinkaku Teahouse on the grounds to experience a traditional tea ceremony.
