This a small market area near the spawn area on my server. Devileye98__ decided to start a community project to build this market area, but due to miscommunication two separate market areas were created, so far only the first of those has been completed, by myself and a team of other players on the server. The idea of the market is that players can build shops where they could engage in item trading (in person as we are a vanilla server and don't have any shop plugins) and we will probably set up some redstone vending machines and villager stalls too.
The groundwork for the first area, called Plaza A for now, is complete and we have 6 different plots available where people can set up their own shop, the plots surround a central square with a rather 'pretty' creeper fountain.

I will update this post as people start to build their own shops and as area B progresses.
