The Weston part of Southampton is across the River Itchen from Southampton, crossing the Itchen Toll Bridge which some see as a barrier and others as a quick and easy crossing into town.
If you're walking you go free. Weston is trying to be a seaside resort with shelters on the rather stony beach on the rather polluted Southampton Water. These have recently been done up with scenes from Southampton's history including the second world war bombing (!) although they lack the old (1980s) slogan of the city 'Southamp-tons more'. My usual walk leads from Sholing to Woolston, down to the shore, up to Netley (more later) and back via Mayfield Park. mayfield park has an obelisk in it bearing the legend 'The earth is the LORD'S and the fullness thereof'. It is a memorial to a whig politician although you'd never know it, mostly just an eye catcher in a bleak part of the park. Mayfield park always seems as though it has a time warp in it because walking through it seems to deliver me with speed to my destination (Thanks Jon and Ray!). It's always much quicker than walking towards it.
Netley is a little village on Southampton Water with a ruined abbey, not as fortunate as Romsey - perhaps they couldn't afford the price if it was the same. Closed at all times except Sundays from 1300-1600 due to antisocial behaviour among the ruins (my mind boggles - What on earth are people doing there?).
The ruins are quite intact as is Netley Castle, once a convalescent home but now a private block of flats with the gardens suitably fenced. Once they were open for all to wander at will.
