One such tribute, a sculpture titled "Wounded but Still Standing in Front of the Inconceivable," consists of two 66-foot-long horizontal platforms that bend into the air.
Another statue, “Flight in Mind,” by Olivier Strebelle, was once housed in the departure hall at the Brussels Airport and was damaged during the attacks, according to The Brussels Times.
That statue was restored and received a grand unveiling today, the first anniversary of the violence.
The attacks were the deadliest terrorist attacks in the country's history.
Thirty-two people died, and over 300 others were injured in three bombings that took place on that Tuesday morning.
Belgium's King Philippe today urged citizens to listen to one another and draw lessons from the "deadly madness" that led to the violence, according to The Associated Press.
"It's the responsibility of each and every one of us to make our society more humane and more just," he said while commemorating the victims. "Let's learn to listen to one another again, to respect one another's weaknesses."
