Dalečín Castle, Medieval castle ruin in Dalečín, Czech Republic.

Dalečín Castle is a fortified ruin positioned on high ground within a bend of the Svratka River, naturally defended on three sides by water. The remains show different building phases, with visible stone walls, foundations, and defensive structures from various periods.

Vznata of Tasov built the castle after 1349, and it was first documented in 1358 when Klara of Tasov and her brother-in-law sold Dalečín to Jimram of Pernštejn. The claim that Moravian captain Archleb Vranovský of Boskovice took and razed it in 1519 rests on no reliable source and comes from Baroque historians. By 1588, when Jan of Pernštejn ceded it to Pavel Katharýn, it was listed as deserted.

The castle's name Tolenstein appears only in 19th-century topographical works and is not historically documented. After the site was abandoned, a new farmstead with a small fortress arose beside it, renewing the tradition of a noble residence in Dalečín.

The ruins are accessible via marked hiking paths that form part of regional trail networks crossing the area. The terrain is hilly and paths can be muddy after rain, so proper footwear is recommended for a comfortable visit.

The name Tolenstein, still sometimes used, appears only in 19th-century topographical works and is not documented in any historical source. The ruin stands on a rocky spur above the Svratka, and its walls still show three storeys with window seats set into the recesses.
