Why it looks like this

Pune was the seat of the Peshwas, prime ministers of the Maratha empire, who ran it from Shaniwar Wada palace (1732). The old city they governed is organized into peths — wards, each with its own market day, and several simply named for those days: Somwar (Monday), Mangalwar (Tuesday), Budhwar (Wednesday) and so on.

After defeating the Marathas in 1818, the British placed their cantonment to the east and 'camp' life apart from the peths — a two-centre pattern still visible. Around both, modern Pune boomed into an education and IT capital, spreading across the Mula and Mutha rivers into a ring of once-separate villages.
