It certainly wasn't attractive. I remember a childhood of sailing out of the mouth of the Beaulieu River and there on your port side was 'heavy industry'. The resi development due to eventually be built there will be quite interesting. It's spearheaded by some er, 'interesting' individuals so should come with plenty of scandals and tittle tattle for the natives over the next decade.
But I've certainly used the tower all my life as a key reference point for heading home in the Solent. It'll be a shame to see the ugly old eyesore go.
