It is strictly forbidden to construct a Hamlet, or to construct or upgrade a Military or Religious building over a River square. Only Towns and Cities may occupy River squares.
The Forest
•When playing with two or three players, if the construction or upgrade of a building covers at least one forest square, the player must spend one additional Construction card of any color they wish.
•For 4 and 5 player games, the forest has no effect.

•When playing with two or three players, if the construction or upgrade of a building covers at least one mountain square, the player must spend 2 additional Construction Cards of any color(s) they wish.
•For four player games the cost is 1 additional Construction card.
•For five players, the mountain has no effect.

A building can only be upgraded if the upgraded building tile is available in the stock pile.
Different smaller buildings cannot be grouped together for an upgrade.
The green player cannot upgrade two Chapels into a single Monastery.

One may only link domains through upgrading or construction of Civil buildings. It is forbidden to construct or upgrade a military or religious building that would link two or more domains.
23. . Demolishing a small building
A player uses Construction Cards to demolish and destroy any size 1 building (Hamlet, Chapel or Watch Tower) whether it is controlled by him or not.
•Demolition requires that the player spend one Ecu and one Construction Card of the exact same color type as that of the building to be destroyed.
•The Hamlets printed on the game board and the buildings of a size greater than 1 may not be demolished.
A demolished building might provoke the separation of a domain
