^^ The first picture of Urwa - Ashoka Nagara area is taken from the top of Lady hill- Chilimbi hill ridge. The river is Gurupura river (aka Phalguni river) which runs parallel to Arabian sea and forms a sandpit in between the sea and the river called Bengre. The east-west flowing Gurupura river takes a right turn near New Mangalore Port, during Tippu's time it used to join the sea at Sultan Battery, now it joins Netravathi river further down near Jeppu before joining the sea. The state government has a plan to develop Bengre, Taneerbhavi area as a tourist destination by developing a golfcourse, a marine park, a ropeway across the river, etc. Also, there is a plan to develop a ring road or marine drive road called Mangala Corniche running parallel to the rivers. The north and east of Mangalore are getting more & more urbanized and so this may be one of the last pictures capturing greenery of this place.
The second picture, as already pointed out by Scorpiogenius, is of Hampanakatte area, taken from a building (Hotel Poonja International?) on K S Rao Road. Hotel Taj Mahal is at extreme left, brown building Hotel Dhanyavad is at the centre. The place in between Hotel Dhanyavad and Hotel Poonja International was old main bus stop of Mangalore and now it will be developed as a parking cum commercial complex. The big building behind Wenlock hospital, and behind the street light is Mohtisham - The Presidium at Attavara circle.
The third picture is of Hampanakatte and Lighthouse Hill (ಬಾವುಟಗುಡ್ಡೆ) area. The picture might have been taken from a building (Mohtisham - The Presidium?) at Attavara Circle. Shortly this view is going to be obstructed by Presidency Skycourt, a 15 storeyed building, coming up in between Mohtisham Presidium and Mohtisham Shamoon Palace.
