Both the Czech name Košťany and the German name Kosten were derived from the old Czech word chvosten. The word chvost literally means 'tail', but in Old Czech it figuratively also meant 'thicket', 'bush'. Chvosten denoted a hill or a forest with thicket or bush.{{cite book |last=Profous|first=Antonín|title=Místní jména v Čechách II: CH–L|url=https://mjc.ujc.cas.cz/search.php|page=325|year=1949|language=cs}}

The village of Střelná is located on the railway line Most–Moldava, but the line is only in operation on weekends.

The only monument in the town is the Košťany Castle. It was built in the Historicist style at the end of the 18th century. It served as a hunting lodge of the Lobkowicz family and later as their summer residence. Between 1919 and 2010, it served as apartments. It is privately owned and inaccessible.{{cite web |title=Zámek|url=https://pamatkovykatalog.cz/zamek-1251871|publisher=National Heritage Institute|language=cs|access-date=2023-06-29}}
