The Igeler Säule, the largest existing pillar tomb north of the Alps, has survived to the present day due to a misconception in the Middle Ages. A family scene depicted on the grave was interpreted as showing the marriage of the parents of the Emperor Constantine, who was honoured together with his mother Helena as patrons of the Christian faith. This mistake ultimately prevented the Roman monument being torn down.

The 23-metre-high pillar is on the UNESCO World Cultural Heritage list, and has impressed such famous visitors as Johann Wolfgang Goethe, Crown Prince Friedrich Wilhelm IV, Victor Hugo and Friedrich Schinkel. The sepulchral monument to the Secundinier family was erected along a street close to the River Mosel around 250 CE, thus displaying the wealth and success of this family of cloth merchants to every traveller up to the present day. The scenes depicted offer insights into the merchants' everyday existence and business life.

The date of origin of the pillar identifies it as one of the last of its kind: subsequently, the Roman city of Trier met with difficult times and its prosperity dwindled. The prestigious grave was an expression of the cloth merchants' entrepreneurial pride. The grave was attributed to the Secundinier family of cloth merchants, mainly because this trade was depicted on the pillar. Over the centuries the pillar has been constantly exposed to the elements. The first structural reinforcement of the pillar grave took place in 1765. In the 20th century this was followed by the creation of a replica in artificial stone, because the original pillar was in absolutely critical condition. Attempts to prevent consequential damage to the original began in the 1980s. The replica pillar was coloured in 1993 based on traces of paint on the original. Unfortunately, this copy could no longer be renovated and had to be dismantled at the end of 2021. The plates of the cast have been placed in storage, with a new permanent copy to be rebuilt on the same site.
