St Patrick's Tower, Former windmill in Thomas Street, Dublin, Ireland

St Patrick's Tower is a former smock windmill on Thomas Street, near the corner with Watling Street, in Dublin. It is a tapering brick tower, part of The Digital Hub and listed in Dublin City Council's Record of Protected Structures. Its copper cupola and a weathervane showing Saint Patrick holding a crozier were added in the late 19th century.

St Patrick's Tower was built in 1757 as a smock windmill powering the Thomas Street Distillery, and it was rebuilt in 1815. The structure is listed in Dublin City Council's Record of Protected Structures and now stands within The Digital Hub.

The tower's name comes from the late 19th-century additions at its top: a copper cupola and a weathervane showing Saint Patrick holding a crozier. The structure is listed in Dublin City Council's Record of Protected Structures and now stands within The Digital Hub, a technology district on Thomas Street.

The windmill is visible from the street, but the interior is not open to the public since it functions as an office building today. Morning light works best for viewing and photographing the structure, as it highlights the dome and architectural details clearly.

The tower's name comes from a late 19th-century addition: a weathervane on top shows Saint Patrick holding a crozier, and the copper cupola was added at the same time. Look up at the roofline to spot the figure, which gave the former smock windmill its present name.
