Answer
The qulla is a ceramic vessel suspended high on the site, fed automatically by a small pipe branching off the water network, providing a constant water source for birds. Its value lies in its material: earthenware keeps water cooler than fast-heating containers and allows limited natural exchange through its porosity. It is a compressed illustration of the whole site’s philosophy — no rejection of technology and no break with heritage, but an intelligent joining of the two into a low-cost, applicable environmental function.
