|Arc de Triomphe|
|DLC||Deluxe Upgrade Pack (or Cities: Skylines Deluxe Edition)|
|Building Type||Unique Building|
|Milestone Required||Worthy Village|
The Arc de Triomphe is a Landmark unique building that comes with the Deluxe Version of Cities: Skylines (or the Deluxe Upgrade Pack DLC for the standard version of the game).
To unlock the Arc de Triomphe, you need to have 7,500 children in elementary schools in total. You’ll also need to reach the Worthy Village milestone (240 – 950 population, depending on the map)
Once these are accomplished, you can build the Arc de Triomphe from the Landmarks tab of the Unique Buildings menu for ₡160,000.
Until then, you can hover over its silhouette in the menu to check your progress towards unlocking it.
Placing Elementary Schools
In the base game, your only option is the standard Elementary School (which has vanilla and “European” assets; these differ only in appearance).
Green Cities and Plazas & Promenades gives you more options for elementary schools.
|Building||Build Cost||Unlocked At||DLC Required||Student Capacity|
|Elementary School||10,000||Little Hamlet||none||300|
|Community School||12,000||Little Hamlet||Green Cities||250|
|High-Capacity Elementary School||26,000||Worthy Village||Plazas & Promenades||800|
How To Get 7,500 Students into Elementary Schools
The only thing you really have to do for this unlock is to grow your population, while making sure you have enough elementary school capacity for all the eligible students.
You can check your capacity versus eligible students by clicking on the Education info view.
Don’t forget—only children can go to elementary school. This means only a small fraction of your population will be eligible.
This also means that even if you’ve recently experienced a population surge due to people (i.e., adults) moving in, you’ll likely have to wait until those adults have kids that can go to school.
Boosting Birth Rate with the Child Health Center
Another thing that can help you out slightly is to build a Child Health Center.
It’s a building that, apart from improving the health of kids and teens, also boosts the birth rate within its radius.
This eventually leads to more children that can go to your elementary schools.
