No bells in the spire- just relics and statues

The cathedral's flèche (or spire), which was destroyed in the April 2019 fire,[60] was located over the transept and altar. The original spire was constructed in the 13th century, probably between 1220 and 1230. It was battered, weakened and bent by the wind over five centuries, and finally was removed in 1786. During the 19th-century restoration, Eugène Viollet-le-Duc decided to recreate it, making a new version of oak covered with lead. The entire spire weighed 750 tons.

Following Viollet-le-Duc's plans, the spire was surrounded by copper statues of the twelve Apostles, in four groups of three, one group at each point of the compass. Each of the four groups were preceded by an animal symbolising one of the four evangelists: a steer for Saint Luke, a lion for Saint Mark, an eagle for Saint John and an angel for Saint Matthew. Just days prior to the spire's collapse, all of the statues were removed for restoration.[61] While in place, they had faced outwards towards Paris, except one; the statue of Saint Thomas, the patron saint of architects, which faced the spire, and had the features of Viollet-le-Duc.

The rooster at the summit of the spire contained three relics: a tiny piece of the Crown of Thorns, located in the treasury of the Cathedral; and relics of Denis and Saint Genevieve, patron saints of Paris. They were placed there in 1935 by the Archibishop Jean Verdier, to protect the congregation from lightning or other harm.
