This is Edutri (Education - Three), it's a large commercial building repurposed for a school building, made in the 1st Segregated Empire. It's built by Skytree Corporation, the same company that made the Eysia Tower, but well, they as a corporation makes everything.
It's a combination of Elementary, Middle, and High school (EHM) for some price and land, and a generally high income
This thing is huge, and even it's insides are.
High Education, Low Education, Some culture in one building.
It also can hold like, 30k+ high education students, and 16k+ low education students.
Yes, it's Expensive... EXPENSIVE, almost a megatheon to build, and some ten thousand theon to keep, but it's real nice. You can only build 10 of them, though, it's balancing :)
It's a 670m tower, it would've been an office building, but here it is, a large-sized school building.
NOTE: This building takes quite a ton of money to upkeep, so don't overuse it so you don't crash your market
