The Hippodrome Carceres provides population, happiness and produces coins in 24 hours. Depending on the building's level additional resources like medals, Forge Points and goods are added to the production. The coin production is doubled upon motivation and is affected by the town's happiness and by boosts of certain Great Buildings.
Chariots will roam the hippodrome if this building is properly connected to the Sphendone.
Neither the Carceres nor the tracks need to be motivated/polished to get the resources of the tracks added to the Carceres.
The amount of tracks added to the building is only limited by the players city size and availability of tracks. The additional tracks have to be correctly aligned and can be attached only to the rear.
Risk of Plunder
As the Hippodrome Carceres does not produce special resources upon motivation, it has a low priority in the motivation order and will only get motivated randomly with the regular buildings after all special buildings that produce forge points, goods, guild power, medals, or blue prints have been motivated. Use a Self-Aid Kit if you want to make sure your Hippodrome Carceres (including the production of attached tracks) is protected from plunderers if you cannot collect on time and you have regular plunderers coming along.
The 'city shield', in the tavern Shop of the friends tavern can also be used to protect from the risk of plunder.
The Hippodrome Carceres can be upgraded by Hippodrome Carceres Upgrade Kit item. To upgrade the Hippodrome Carceres, use the Hippodrome Carceres Upgrade item on the Hippodrome Carceres that is already situated in your city. Its upgraded version will then be placed directly on the same spot in your city and the production timer will not be reset. Note that the upgraded building will be from your current era, even if the old one was from one of the earlier ages.
