The post you are reporting:
Sorry, Paul, I confused the Grand Shaft for the Drop Redoubt.
My apologies. The Drop Redoubt was repointed for £250.000. as you rightly point out.
Although the initial estimate to get it to A1 standard was £10-20 million.
As we can see, essential works can be carried out for a lot less than it would cost to get the whole area of Napoleonic sites on Western Heights up to A1 standard.
So if we're looking at getting essential works done, we might be talking of a few million pounds every 10 years or so, enough to keep the defensive sites from decaying.
This would be a far better option than investing tens of millions of pounds in the Drop Redoubt, tens of millions in the former barracks area, tens of millions in the eastern moats, tens of millions in the western moats and so on.
So what I am asking, is what you estimate should be done, a A1 achievement for the whole Napoleonic area for £100 million, or an essential upkeep job for a few million pounds?
Unless we know this, it's hard to keep an overview of what you consider should be spent up there.
