Monument

s are towers that appear in Sonic Boom: Rise of Lyric around Bygon Island area.

They are the objectives to Perci's mission in Sonic Boom: Rise of Lyric.

Description
They resemble large towers possitioned on the beaches outside the town walls. When activated the round top part of the towers (refered to as "balloons") will levitate upwards while the towers produce a pillar of light towards the balloon. Under the balloons, turrets can be visable.

When all of the monuments are activated, they serve as defence to Bygone Island.

Sonic Boom: Rise of Lyric
After retrieving the Verdant Crystal from Slowpoke Isle, Perci will give Team Sonic a mission for them to earn her trust.

The ojective is to activate the three monuments located outside the town.
 * East of the archway starting point.
 * West of the town.
 * One located in Coral Bay

Activating
The monuments have rotary walls that need to be rotated in order to activate the tower. To do so there are three Enerbeam switches that when pull will spin the tower walls to reveal three green buttons.

Once the three buttons are pressed, the monuments will release it's balloon, allowing it to float high up over it.

Trivia
Perci regards them as ancient monuments, whenever she means they were constructed by the Ancients or to be taken literally is unconfirmed.
