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.
Archumen was also hosted in Pakistan in October 2010 at the National College of Arts at Lahore during the Students' Jamboree at The Asian Congress of Architects - ACA 14.
