Las Covachas are located on Cuesta de Belén street in Sanlúcar de Barrameda , attached to the retaining wall of the Jardín de Los Limones (Garden or Promenade of the Lemons) of the Ducal Palace of Medina Sidonia, also known as the Palace of the Guzmanes , and next to the popular market.
They consist of ten arches resting on Gothic-style pilasters adorned with unusual marine mythological figures. Although their original function is unclear, they appear to have formed part of the original façade of the Palace of Medina Sidonia, like the Puerta del Mar (Sea Gate).
Las Covachas were commissioned by Enrique de Guzmán, the 2nd Duke of Medina Sidonia, at the end of the 15th century. They were declared a historical-artistic monument in 1978, along with the Ducal Palace of Medina Sidonia.
