We first unleashed our London-for-free map about a year ago, back when Robert Peston was still perfecting his hand gestures and we all had money to burn. With the economy plummeting like a calcified lemming, it seems a good time to wheel it out again. We've plotted all the venues about town that offer some kind of free entertainment: mostly museums (red), galleries (green) and regular talks (blue). Click each marker for more information.
Most importantly, leave a comment if you think something is missing from the map.
