And I assume shipping-cost is not included in the price shown, or is it?
Luckily for my wallet my playmo-world is mainly focused on Carribean adventures which have no need for such expensive cathedrals!
(Big sailships however )
PS: Real medieval cathedrals were also so expensive, it sometimes took centuries to complete them (and some never got the finishing touches)
Shipping would be a lot I would think.
The cathedrals were also built using a lot of volunteer labour so it kept costs down and made the builds go faster. They were built for the community even if the rationale for initial funding was to increase the prestige of the Church and the local patricians.
