The museum collects interior objects from manor lord houses, urban and rural household objects, as well as crafts and tools.
Some applied arts objects were obtained in the first years of the museum or before the museum was founded, but it was only after establishing a Local History Research Department in 1958 that collecting objects of cultural-historical significance began in earnest.
In the vast assortment of the late 19thand early 20th century ethnographic items, the pottery of Jānis Krievs stands out with the diversity of colours and shapes.
The museum also collects works by the Decorative Folk Art Studio “Durbe”, with special attention to national costumes from Tukums, Engure, Jaunpils and Kandava municipalities. Restorers of cultural-historical monuments benefit greatly from samples of architectural details and decorative ornaments.
The museum is in the possession of several objects from the Tukums Evangelical Lutheran Church of the Holy Trinity, including a Mannerism chandelier (early 17th century) and offering vessels made by goldsmith J. D. Linters (18th century).
Interior objects are collected and restored to depict the historical environment at Durbe Manor (19th/20th century), Džūkste Fairy Tale Museum (early 20th century) and Pastariņš’ Museum (mid-20th century).
