We are sharing textures under CC0 Licenses for more than 2 years.
We have 850+ free PBR Textures up to 4K resolution. Most of the textures are seamless and they are coming with diffuse, roughness, metallic, ao, displacement/height maps. You can find mostly architectural textures in our library.

I hope our textures help you with your projects.
Here some of the preview renders.
