The most remote settlement of Háromszék is Zalánpatak, hidden by the forests. The place of this village was originally called Egyedmezeje. There was a greenhouse established here at the end of the 17th century, which operated until 1860. As the forests belonged to Zalán, the site was originally called Zalávi Glass Barn. Currently administratively, it belongs to Málnás. Every small area here is taken from the forest. If a piece of plowed land was not cultivated for a few years, then the forest would embrace it again.
The area is not suitable for intensive farming, therefore here there were no cooperative farms at the time of the communism, and thus everybody farmed their own land. Because of the local conditions, grass farming has a greater role than farming. Good forest pastures and grassland are the cornerstone of dairy cattle farming. Due to the traditional village lifestyle, old barns and stables have survived, and most of the residential buildings are popular architectural monuments. The wooden veranda houses with stone foundations are characteristic to the village, and in many cases, they still have the old traditional tile pointed Bacon tile. No wonder, that Charles, Prince of Wales bought a house in this quiet traditional village, and once a year comes here to relax.
