Asclepeion

The Spartans' own Hospital, recovering wounded troops the same way but keeping a larger share of them.

• Up to 60% of what the village loses at home comes back wounded, against 40% for an ordinary Hospital - half as many again.
• Infantry and cavalry share one queue, as they do in a Hospital.
• It also produces more culture points per level than the Hospital does, which is worth something in a defensive village that is short of them.

The maths. Healing runs on the training curve at half speed: base training time x 0.9^(level - 1), divided by the world's speed, then halved. A Legionnaire that takes 0:10:20 to train at level 10 takes 0:05:10 to heal at that level. Nothing that speeds training up touches it - not an artefact, not a helmet, not Alliance Recruitment, not the Romans' Horse Drinking Trough - which is the easiest thing here to get wrong. Infantry and cavalry share one queue, and siege, settlers, administrators and the hero are never wounded at all.

Strategy. The extra twenty points are worth most while the recovery queue is still moving. Late in a round a single large battle can wound more troops than the queue will get through in any useful time, and once it is saturated the higher share mostly lengthens a queue that was already too long - the building is no worse, but the advantage stops converting into troops on the wall.
