Let's take a little trip through Europe, shall we?
Each level forms a word chain. Even-numbered levels (yellow) go clockwise, odd-numbered ones (white) go anticlockwise.
Each level has an answer which points to a certain region of Europe. This answer always covers the two central squares of the left column when the answers are put correctly in the grid.
The seven regions are the BRITISH isles, the IBERIAN peninsula, the BENELUX countries, CENTRAL Europe, the BALKANS, the BALTICS, and EASTERN Europe (not necessarily in this order).
The final answer is a landmark. The grid below can be used to find out the country where it's in. (This may be useful, but the final answer can be solved without it.)
