Solca (Polish: Solca, German: Solza) is an abandoned village within the municipal borders of the Doly District in the town of Karviná in Karviná District, Moravian-Silesian Region, Czech Republic.
Solca was one of the oldest villages in Cieszyn Silesia. A document of Bishop of Wrocław issued on 23 May 1223 for Norbertine Sisters in Rybnik includes a following excerpt:
Decimas videlicet ipsius ville Ribnich, Smolna, Zalese, Knegnizi, quam ultimam villam recepit ecclesia de Ribnich ab ecclesia de Sale, in concambium pro villa Golconis
Except for Sale all the mentioned villages were lying in the vicinity of Rybnik, thus it is problematic to localise where the settlement was supposed to be. Some historians identify it with Solca. The village had already a church (ecclesia), undoubtedly one of the oldest in the region, perhaps built during the reign of Mieszko I Tanglefoot. Again the village was mentioned in 1229 in the document of Pope Gregory IX issued for Benedictine abbey in Tyniec as Sal, leaving no doubts to its localisation close to Orlová. The village with an inn was endowed to Orlová abbey founded in 1268, and attested in the associated document again as Sal. In the next centuries the name of the village evolved into Solec/Solca.
Politically the village belonged initially to the Duchy of Opole and Racibórz and Castellany of Cieszyn, which was in 1290 formed in the process of feudal fragmentation of Poland into the Duchy of Teschen, and was ruled by a local branch of Piast dynasty. In 1327 the duchy became a fee of Kingdom of Bohemia, which after 1526 became part of the Habsburg Monarchy. Before the end of Middle Ages ownership of the village had changed, first it became a propriety of the Cieszyn dukes, then of noble families. In 1570 it belonged to Jerzy Larisch from Lhota, the owner of Karviná. The Larisch family gradually enlarged their belongins, since 1730 administered as fideikomis.
