A three-tiered ancient tower with a squared base, octagonal middle, and cylindrical top. The tower has a stone texture with slight cracks and wear, showing its ancient but not ruined state. Each level has small windows or arches. At the top, there is a glowing fire or torch with gold/yellow and orange rays. The base of the tower is surrounded by blue waves lapping at it. The color palette consists of sandstone (beige/tan) for the tower, turquoise/blue for the sea, and warm gold for the fire. The style should be vibrant and detailed, capturing the essence of an ancient beacon by the sea.illustration
