Bavarian Castles

Divide the grid into seven provinces, each consisting of seven orthogonally connected cells. Every row, column and province must contain the digits 1 to 7 once each.

Every province contains a Castle (circle). The seven castles form a set of the digits 1-7.

Digits in caged cells indicate how many cells of the same province are seen orthogonally from that position, including itself. Other provinces block vision.

Green lines cross province borders, separating two digits that differ by 4 or more.
