Some statues and remains of pottery and fabrics can be seen scarcely due to grave robbery before the hypogea were constituted as protected areas.

The details in the sculptures and pictorial patterns in the hypogea are similar to the neighboring San Agustín culture, although they occur at much higher density.

The mountainous area where the Tierradentro culture thrived and the excavations of 162 hypogea now comprise a national archeological park in the jurisdiction of the municipality of Inza, Department of Cauca, Colombia.

[1] The Terradentro National Archeological Park was listed as a UNESCO World Heritage Site in 1995 because of its "unique testimony to the artistic and social culture of the region".

[1] The park generates significant revenue to the local economy due to the high volume of tourists, both Colombian and foreigners.
