Swedish imperial coastal fortifications are a personal choice for defenses especially impressive by the standards of their era.

Their similar design and different appearance reminded him of his mother and aunt, who are nonidentical twins. The paired forts therefore have a personal significance distinct from the assessment of Swedish defenses.
