I just thought of a large mausoleum for some reason. Here is a description (this is my imagination, not real): It was a huge, towering mass of marble with granite making up the floor that led to the jeweled entrance. There was a serpent of gold, with sapphire eyes, that guarded the mausoleum, a wolf of silver with emerald eyes guarding the Inner Tomb, and lastly, the coffin itself, covered with amulets, so that you could barely see the rich mahogany lid or the oak bottom or the bronze hinges. The sides were of sturdy oak as well. The body inside, whether by witchery or some other strange art, had been preserved, and was pale and waxy.
To be honest that was more of a description of some sort of pyramid but I think it still ought to be a mausoleum.
