Here are some unusual looking temples. In the package you will find:

-Two temple variants
-Dome overlays
-A cross to top the domes
-Small tower
-Large tower
-Small and large tower overlays

You can mix and match stuff to create some variations on how these temples look. I personally really like using cset 8 in DoR to make golden tops for the temples. The temples look best in cset 3 or cset 11, imo, but obviously you can make new palettes or use them in other tilesets however you like.

The shading is not going to match everything in your tileset, but most tilesets have shading clashes within them anyway.

(I like these as dungeon entrances, btw.)

The package is in DoR cset 3.

These are from RPG Maker, I think, in any case they are all over the place online.
