It resembles the Casa Grande ruin of Chihuahua, Mexico, with its walls of sundried puddled clay, and its area of rooms, courts and plazas, surrounded by a wall.
A number of handsomely-laid-out plazas, or squares, ornamented with gardens and statuary, have been preserved; on these face the principal public buildings and churches.
There are seven plazas, or squares, within the urban limits: Zabala or Rincon, Constitucion or Matriz, Independencia, Libertad or Cagancha, Treinte y Tres, Flores and Frutos; and two suburban parks or public gardens: the Paseo del Prado and Parque Urbano.
The most notable of the plazas are Military, Main and Alamo.
In the Cathedral Square (Plaza de Armas), embracing two citysquares, and shaded - like all the plazas of the island - with laurels and royal palms, are a statue of Isabel the Catholic, and two marble lions given by Queen Isabel II.; elsewhere there are statues of General Clouet and Marshal Serrano, once captaingeneral.
