Re: Dil walon ki Dilli
It was muhammad bin tuglaq, Pagal Badshah, he changed his capital from Delhi to Devgiri.Daulatabad as it was near to deccan and was in Central India, now maharashtra but western border was too far then he had to return to dilli, he also started rubber coins but dilliwalahs started duplicating it:D
Lal quila has various gates, Ajmeri gate, Kashmiri gate, Lahore gate, I think there are twelve gates, Kashmiri gate has Inter state bus terminus hence for daily travellers, travelling towards north of delhi it is very important area
