Whether you prefer eerie, gothic, or playful vibes, your fireplace mantel and hearth can transform your home into a festive haunt. Here are 22 large Halloween fireplace decoration ideas that are simple, creative, and perfect for impressing guests.

Line your mantel with tall black candles in antique holders. When lit, they create a flickering haunted-house glow that enhances the eerie mood. For safety, flameless LED candles work perfectly.
