We hear a lot about Piergeron’s Palace in Waterdeep, but to my knowledge no official maps or walkthroughs of it exist (and only one image). Are there any interesting features inside it as of 1491? Anything from magic items to impressive tapestries. Thanks! Full maps are owned by TSR (now Wizards) and so are NDA. There are some room and layout descriptions in DEATH MASKS, en passant rather than formal, as the action unfolds. Yes, there are secret passages, some permanent magical effects and defenses, and several animated sculptures.
