Ethos commenced its journey in 2002 with Archumen - India's Biggest Architecture Quiz for students of architecture. Moving on from a modest beginning at The Town Hall in Kolkata, Archumen travelled to Sri Lanka where an edition was held in Colombo . Archumen has made reading a habit once again and the library a popular haunt of the students.
Archumen is conducted as a four-zone quiz that culminates in a Grand National Finale. The research by Ethos ensures that students are exposed to relevant and valuable information from the construction world.
