Many of the artefacts discovered at Alacahöyük, including magnificent Hattian gold and bronze objects found in the Royal Tombs, are housed today in the Museum of Anatolian Civilizations in Ankara. Among these artefacts are gold and electrum standing cups and other vessels. The most unusual are the Alaca Höyük bronze standards; bulls or stags on pedestals whose purpose remains the subject of debate. The standards are cast in copper, many in the form of flat circles, half-circles or squares that are filled with an openwork network of cross bars, central crosses, and swastikas. Leonard Woolley found that the Royal Tombs "seem to belong to the end of a period, as marked by a stratum of destruction and the burning of the citadel. The culture which the tomb objects illustrate does not continue into the next historical phase, that of Kültepe". Modern assessment finds that the site continued as a flourishing community to the end of the Late Bronze Age. There was also a sizable occupation in Phrygian times.
