These Ancient Temple Ruins have been created for a modular game environment but they are a great collection of high poly objects that can be used for your project. All of the objects have been sculpted inside 3D Coat using voxel sculpting techniques. This means that almost all of the meshes consist of solid stone bricks that can be moved around or be hidden.

Meshes have been decimated but still are fairly heavy. Triangle count is between 200k to 4mil with 1-2 mil on average. Obj archive is about 400mb in size. The assembly scene is not included in the package as it was about 12 gigabytes in size. So it is only a collection of separate objects.

They are heavily relying on a Fotoref Angkor Wat photo reference pack - https://www.fotoref.com/products/angkor-temple -but were not intended to be a temple reconstruction.

Feel free to use it in any of your projects.
