Kaytower

Kaytower was one of the earliest big builds of Syberia, and lasted until September of 2018. There were two Kaytowers, one in the original server and one in the main server. Both has been demolished.

Features
Kaytower was a 255-block high cylindrical tower made primarily of stone bricks. The first Kaytower was hollow, with little inside before it was blown up. The second tower, in the main server, was mostly hollow, except for a top room containing an emerald statue of Buddha. Players could access this top floor via a command block elevator or the built-in rollercoaster.

The Kaytower Incident
On September 8, 2018, Tungsten used WorldEdit to change Kaytower into TNT as a joke. Before they could reverse it, someone stepped on a pressure plate, which blew up the tower and destroyed much of the surrounding area. In an attempt to reverse the damage, Burrito tried to insert a backup, but ended up deleting the world. As such, Syberia was reset, beginning the current iteration of the server.

One theory that became popular is that the detonation was not caused by somebody entering, but was instead caused by the rollercoaster inside the tower.
