Religious relics are a rather interesting thing. One I’ve always found strange can be found at the Basilica of Saint Peter in Chains. Here is an excerpt from their web site.
The pious Eudocia, wife of Emperor Teodosio II, journeyed to Jerusalem and found the chain that had bound Peter during his second imprisonment. According to the Acts 12:6, an angel caused the chains to fall from Peter's hands and led him past slumbering guards to freedom.
The chain was eventually given as a gift to Pope St. Leo the Great (440-461). In Rome there was already a chain that was greatly prized which had bound the saint during his nine month imprisonment in the Mamertine Prison near the Forum. When the pope compared the two chains, they miraculously fused together into one unbreakable series of links. Because of this miracle, Empress Eudocia built the Basilica of Saint Peter in Chains, and dedicated it to the apostle in the year 442. The relic is now kept in a golden urn beneath the high altar, close to the famous statue of Michelangelo's Moses.
