Tvrziště Smiřično, Medieval stronghold in Mříčná, Czech Republic.

Tvrziště Smiřično is a vanished stronghold in Mříčná, near the confluence of the Buranka stream and the Mříčenský brook by the local swimming pool. Its motte-type site is an oval, grass-covered mound about two metres high. The site is protected as a cultural monument.

Smiřično is first mentioned in 1356, when Jan and Oldřich of Smiřično are recorded. In the early 15th century Jan Tichava of Smřečno held it, and the stronghold later passed to the lords of Pecka and then to the Waldsteins. In 1439 Jan of Waldstein and Smiřično is named there; Felix of Waldstein held it until before 1476, when Jindřich of Waldstein attached the village to the Jilemnice estate. The stronghold was abandoned soon after and was no longer mentioned in the 1492 division of the Štěpanice estate.
