This trio of mammoth timber funnels is designed to magnify the natural sounds of a forest in southern Estonia, and to double up as a space for ramblers to contemplate and rest.
Created by a group of interior architecture students from the Estonian Academy of Arts, Unplugged Kingsize Megaphones is installed in a densely forested site in the Pähni Nature Centre, near the Latvian border.
The structures were built off-site by the students in Estonia's Medieval capital Tallinn, before being transported to the site.
The megaphones were then positioned around a small clearing, creating a "bandstand" for the sounds produced within the forest.
Measuring three metres in diameter at their widest point, each structure is large enough to create a lounging spot for several people.
"At the centre of the installation, sound feeds from all three directions should create a unique merged surround sound effect," said department leader Hannes Praks.
"The megaphone installation provides an excellent opportunity to experience the meeting of contemporary architectural space and wild nature, and it is freely accessible for foreigners as well as local travellers."
The project has its origins in a workshop carried out in the woods by Derelict Furniture designers Tõnis Kalve and Ahti Grünberg and Aet Ader, Karin Tõugu, Kadri Klementi and Mari Hunt from architecture studio B210.
The workshop leaders asked the interior architecture students to come up with concepts of a forest library with Valdur Mikita, an Estonian author who writes about the importance of forests to Estonian culture.
Birgit Õigus designed the winning proposal, which was then constructed with the help of fellow students and installed on the site in September 2015.
"It's a place to listen, to browse the audible book of nature – there hasn't really been a place like that in Estonia before," said Mikita.
