Scottish artist Aeneas Wilder has completed a new site-specific art work in Borgloon, Belgium. Untitled #158 is an architectural structure in the landscape near the Monastery of Colen, a round construction with a 360º view, composed of uniform vertical wooden slats. To enter the artwork is an experience intended to refer to religion and remind you of walking around a monastery. According to Wilder, this work "functions as a lens with which the visitor can focus his thoughts and emotions, capturing the landscape of Borgloon as a background."

Untitled #158 is part of of Z33's Pit art in public space program. The initiative commissions site-specific art that dialogues in a formal as well as an intrinsic way with the environment. Both Belgian and international artists encourage passers-by and visitors to take a different look at the environment. Other artworks of the project include Gijs Van Vaerenbergh's Reading between the Lines seethrough church, Tadashi Kawamata's Burchtheuvel project, Dré Wapenaar's Tranendreef hanging tents in trees, and Wesley Meuris' Memento.
