The Brunswick Monument is a Gothic mausoleum on Geneva's lakefront, built not from civic pride but from a duke's grudge. Karl II of Brunswick was deposed and exiled in 1830 for being, as one tour guide puts it, "too extravagant for his time." He spent his final years at the nearby Hôtel Beau Rivage, died in 1873, and left Geneva his entire fortune. The condition: build him a tomb modelled on the Scaligeri mausoleum in Verona. He attached a drawing to the will.

Geneva obliged. Ten percent went on the monument; the rest cleared the city's debts and funded its opera house. The four corner figures represent virtues: prudence wears three faces for past, present and future; temperance dilutes wine with water; justice holds a sword and scales.

VoiceMap's self-guided audio tours use the monument as their starting point, unpacking Karl's paranoia, his famous 1858 chess match with Paul Morphy, and the unlikely fortune that shaped modern Geneva.
