First introduced in "Pharaoh", the player is often required to erect historic monuments to increase their city's 'Monument' rating or to fulfill a goal. However, unlike normal buildings, which are built instantly, the monuments are gradually built from the ground up, through massive deliveries of construction materials (Like Sand or Plain Stone, in "Pharaoh") as well as 'guilds' of special constructors whom work with a certain type of material. For an instance, when making a Pyramid, stonemasters work with Sand and Plain Stone to place and later gravel the stone, but carpenters and wood are needed to build ramps which peasants from a Work Camp can use to then haul stone loads towards the current level. However, in "Pharaoh", before actual construction can begin, the player must first lay down the site and then Work Camp peasants will prepare it, digging the base into water level. Some particular monuments, like the sphinx, need only a stonemaster to quarry the monument, but all share the fact they take long amounts of time to build, even with the closest materials and personnel available, as well as they need an early massive amount of resources, made or imported via trade.
