Pokémon Tower

That's a Pokémon Tower.

It was located in Lavender Town and it 
was a Home for these 

scary Ghost Pokémon like Gastly, Haunter and Gengar. 

That's an ancient Pokémon Tower in 

the The electric Tale of Pikachu Chapter called "Haunting my Dreams". 

I think Pokémon Tower was a creepy horrible Place for Ash, Misty, Brock and Pikachu 

to enter in the Pokémon Episode called "The Tower of Terror". 

That Pokémon Tower has 2-Horn like Object protruding from the Side of it 

and a Balcony that appears to be 

a Mouth and 2-Eye-like Windows on the very Top of the Tower 

giving it a demonic Appearance. 

So, in the Pokémon Tower, there were several other Balconies 

and Windows on it. 

In the ancient Pokémon Tower, 

there were weird Statues and Windows with no Glass.
