The following list represents perhaps a slightly controversial view of the various "firsts". For this reason, a "confidence" column is included, and where this is less than 100%, then an alternative view may well be possible, and should be passed to the webmaster for consideration. Clicking on the scheme name will bring up a map or picture of the relevant section of the scheme (where available). Click on the browser's "back" button to return to this page.
