The Field of Triumph is a large outdoor stadium located in the Sea Ward of Waterdeep.

The Field of Triumph was the venue for many public spectacles from late spring until late autumn, weather permitting. The Open Lord of Waterdeep used the Field as a public forum to give proclamations to the city, but most of the time it was host to exciting events such as horse races, shows of magic and illusion, martial displays of formation and skill, gladiatorial combats, and exhibitions of strange and wondrous creatures and monsters from all across Faerûn and beyond. Attendance often numbered in the thousands.

This stadium stands over five stories tall. Its main entrance is known as the Lion Gate, due to it being carved to give visitors the impression that they were walking into the maw of a gigantic lion.
