The origin of the name is uncertain, but it may well be connected with the large French community which lived in Waterford from the period following the Battle of the Boyne in 1690.

[1] Many of these people were of Huguenot origin, and their descendants still live in Waterford to this day.

The tower is located at the point where the city wall makes a sharp turn, coming up from Manor Street, past Double Tower, and then continuing in a northerly direction to Newgate Street along Browns Lane.

[2] The horizontal cross section of the tower is kidney-shaped, which offers the maximum defensive view of the wall while occupying the smallest possible space inside the wall.

The upper floors were probably added in the fifteenth century to accommodate small guns and cannons.
