I’ve detailed the good and the not so good of Totnes’ main square here.
The picture below shows how the square is transformed during markets days.
The traffic path shown in the top picture becomes the organizing element; all vendor tents are set up in alignment with the lane. This seems like the right set up as there could be no more than two lanes anyway. I like how the lanes are perpendicular to the High Street. The planters offer some seating but also take up space for at least one tent each. I’m not sure the trade off is worth it.
