Construction workers in Dendermonde, Belgium, discovered a hidden stash of gold coins and bars worth approximately US$10 million [2].

The discovery highlights the unexpected historical treasures that can remain hidden within urban infrastructure, potentially altering the valuation of local sites.

The workers were laying sewage pipes at a site that previously served as a brewery and a homeless shelter [4, 5]. While digging, the crew broke through a cellar wall that concealed the hoard [3, 6].

The treasure consists of gold bars and coins. The estimated value of the find is €9 million [1], which is approximately US$10 million [2]. Some reports place the value slightly higher at US$10.4 million [2].

Reports said that an 18-year-old builder first noticed the treasure, initially mistaking the gold coins for spare change [3]. The find was reported earlier this month on Aug. 14 [1] and again on Aug. 17 [7].

The site in Dendermonde has now become a point of interest as officials assess the origin of the gold. The hoard remained undetected until the current sewer-building project necessitated the excavation of the cellar area [6].

The discovery of a multimillion-dollar hoard during routine infrastructure work often triggers legal disputes over ownership between the finders, the landowner, and the state. In Belgium, such finds may be subject to cultural heritage laws, which could determine whether the gold is treated as a private windfall or a protected historical artifact.
