Indo-German effort

In the fervour of the post-independence era, each of the 5 (at that time) IITs was set up with help from a different soverign nation. It so happened that Madras got the benefit of West Germany's bounty. As a result, here's a road sign that acknowledges the linkage.

Stretching it a bit, I'm willing to bet that Chennai is the only city in India that has so many streets named after foreign cities / localities: Delhi might have its share of personalities, but Chennai, I'm sure is ahead by a long shot - everyone knows Ho Chi Minh of the Delhi Marg, but who remembers the Orme in Orme's Road of Madras?

Bonn, of course, is different. Within the gates of the IIT Madras, going down Bonn Avenue has a charm that can't be replicated anywhere else!
