Wonders that compete for the same tiles

Is it worth building?

Empire-wide growth acceleration — every city grows faster for the rest of the game. The earlier it lands, the more population it compounds into; a classic strong pick for wide early empires.

Placement & timing tips

River adjacency, so most decent capitals qualify. It is only worth the hammers early — as a rule, if Feudalism is researched, the moment has passed.

When to build it — and when not to

Build it when: Build when your cities have housing headroom to grow into — fresh-water settles with farms coming — and your opening is peaceful enough to spare capital hammers in the ancient era.
Skip it when: Skip when housing already caps your cities — accelerated growth into a ceiling is nothing. A builder for farms or another settler converts the same early hammers into actual population room.

Which city should build it

Because the effect is empire-wide and the cost is tiny, the only thing the host city has to be is fast. Any river tile works, and the capital is almost always the right answer: it has the most hammers in the opening turns, it is the city you can chop without delaying a settler elsewhere. Put the wonder on a river tile you would not have farmed, a plains flat without a resource or the far bank from where your districts will cluster, so it does not steal the Commercial Hub's river adjacency spot. If your capital has no river but your second city does, resist the urge: a second city building a wonder in the ancient era stops growing and stops producing builders, and that cost usually exceeds what the wonder returns.

Winning the race

One of the most contested ancient wonders. The AI loves cheap early wonders and almost every AI capital sits on a river, so on Emperor and above it is often gone before you finish Irrigation unless you go straight for it. Treat it as an opening decision: research Irrigation right after Pottery, queue it the turn the tech lands, and chop the two nearest woods, ideally with Corvée already slotted from State Workforce. Egypt's river-wonder bonus makes it practically reserved for that civ. The losing signs are unambiguous: gossip that another civ has started it, or reaching the tech with no builder ready to chop. In that situation pushing with raw hammers alone usually means finishing second and losing the settler you could have built instead.

If you lose it: alternatives

Growth speed can be replaced with housing and food in the right order. The Fertility Rites pantheon gives a similar growth boost plus a free builder, a Granary and a river-side Aqueduct in each city remove the ceiling first, and farm triangles after Feudalism are the larger food source in the end. The most honest use of the freed early hammers is one more settler: another city that will grow under whatever multipliers you do have reaches the same population total by a different route. If you want a wonder from the same window, the Temple of Artemis concentrates housing and amenities in one city and is fought over less. Whatever you choose, the worst outcome is delaying your expansion for a Hanging Gardens you then lose.
