So, Casas del Turuñuelo in Guareña (Badajoz) is probably the most fascinating and important active archaeological site in Spain right now; it is a tartessic site, from the 6th-5th century BCE, extremely well preserved, and every excavation campaign shows incredible findings. Keep in mind, we know very little about the Tartessians, and the core of where they inhabited is either flooded or heavily populated, making it very hard to excavate. This site is at the northern edge of the sphere of influence of the civilization, pretty inland, and that's why it has been able to be fully excavated. I have already made posts about the masks , alphabet, and greek altar that were unearthed in previous excavations, in case you want to take a look at them.
This year, they unearthed this 5th century bronze chariot:

This is a votive chariot, dedicated to an unknown deity, that probably held myrrh or incense, and was used in ceremonies. It is decorated with the head of greek river god achelous between two griffins. here's a closer look at one of the griffins and of achelous:

apart from the greek elements, the structure of the chariot is reminiscent of etruscan ones, which further cements the idea that tartessians had a close relationship with other mediterranean peoples, and that there could even be greeks, etruscans, or other groups, living in tartessos!!! we already know that a lot of phoenicians were settled in this area, so it wouldn't be to far-fetched to assume tartessos was quite a diverse multi-cultural society. It is also especially relevant that all of this appeared far from the oldest and central parts of the culture, in the hinterlands, which indicates that in urban areas this intermixing of cultures was definitely more intense.
here are some relevant articles (in spanish) about the findings: here, here, and here
