How do lighthouse towers resist waves?

 title: 'Technical diagram of a mechanical component.'

Lighthouse towers resist waves through a combination of features[1]. They should have a low center of gravity and sufficient mass to prevent being upset by waves[1]. The towers should be circular in the horizontal plane and either straight or continuously curved in the vertical plane to avoid abrupt changes in outline[1].

When dealing with soft rocks, the tower should have a curved profile to prevent the rock from breaking up due to the waves' reaction[1]. The stones should also be connected and fixed to the rock to prevent being washed away during construction[1].
