The name of the settlement was changed from Laze to Laze pri Boštanju (literally, 'Laze near Boštanj') in 1955[5] to differentiate it from other settlements with the same name. The name Laze is derived from the common noun laz 'cleared area in or next to a forest overgrown with grass'. This was originally a masculine plural noun (preserved in some other toponyms such as Dolenji Lazi), but it became a feminine plural noun like similar toponyms (e.g., Laze pri Dolskem, Zgornje Laže, etc.) due to the ambiguous accusative ending in -e.[6]
Rekštanj Castle
The ruins of Rekštanj Castle (German: Ruckenstein), a medieval castle first mentioned in written documents dating to 1392 and abandoned in the 17th century, lie north of the settlement on a hill above the right bank of the Mirna River.[7]
