The palace map generator draws the state floor of a palace on five-foot squares. Broad marble steps lead up to a columned portico, and the great doors open into the throne room, a long hall down the middle of the building. Two rows of columns line it and a red carpet runs from the doors to the dais, where the throne stands between banners and braziers. Behind the throne are two rooms: the treasury, with its iron door, chests and loose coin, and the grand stair up to the royal apartments. The wings either side of the throne room hold four more rooms, chosen from a banquet hall, a council chamber, a guard room, an open garden court, a royal chapel and a portrait gallery. Some palaces also have a secret passage running from behind the throne to the treasury. Every room is numbered and keyed.
How the palace is laid out
Palaces are built to be read from the door. You enter on the long axis and the whole length of the throne room is in front of you, with the ruler at the end of it. That's the point of the building, and the generator keeps it: the throne room is always central, always entered from the portico, and always the longest room on the plan.
The wings change from roll to roll. Each wing is split into two rooms at a different point, so the rooms come in different sizes, and each room is furnished for its use. The banquet hall has a long table set for a feast and a fireplace on the outer wall. The council chamber has a round table with a map on it. The guard room has bunks, a weapon rack and a table for dice. The garden court is open to the sky, with paths, a fountain and four flowering trees. The chapel has an altar and pews. The gallery has portraits on the wall and statues at either end. Every wing room has its own door into the throne room.
Intrigue, heists and coups
A palace adventure is rarely about the fight. It's about who is in which room. The guard room tells you where the guards sleep. The council chamber is where the plot is discussed, the banquet hall is where it's carried out, and the gallery is where two people can talk unseen. The treasury is behind the throne, so you have to get past the throne room to reach it, unless you've found the passage. The grand stair leads up to the apartments, which is where the person everyone is after actually is.
Free SVG and PNG downloads
Both formats are free for your games, streams and published adventures. The PNG is a 1920-pixel render ready for Roll20, Foundry or Owlbear Rodeo, and the Print button gives you a black-and-white sheet for the table. The SVG is the vector original: open it in Inkscape, Affinity or Figma to swap a wing room, add guards or move the secret passage. Everything on the map is drawn by our own code, so there's no attribution to carry and no asset licence to read.
What it won't do
It draws the state floor. It doesn't draw the royal apartments upstairs, the kitchens and servants' quarters, or the grounds and walls around the palace. For the walls and the outer court, roll a castle map; for the city it rules, a city map.
Name the palace, then walk in
The palace name generator names the palace and writes its history, and draws this same floor plan beside its result with the generated name on the sheet. The kingdom name generator names the realm it rules, the villain name generator names whoever is plotting in the council chamber, and the knight name generator names whoever is guarding the doors.
