It's an high poly stone gate. The model is based on a gate from Fouras in France. [See on google maps](https://goo.gl/maps/gs7gN5R7HzFFLrwC6)
The model has no textures so if you want to create some and repost the 3D model you can. The model is detailed because all of the curves are made of 12 edges, it can still be integrated into a game.
