The Pucará de Tilcara is a pre-Inca fortification or pukara located on a hill just outside (approximately a 15-minute walk) the small town of Tilcara, in the Argentine province of Jujuy. The location was strategically chosen to be easily defensible and to provide good views over a long stretch of the Quebrada de Humahuaca. The Pucará de Tilcara was declared a National Monument in 2000. It has been partially rebuilt, and is the only publicly accessible archaeological site in the Quebrada de Humahuaca.
