Srimad-Bhagavatam: Canto 3 - Chapter 1 - Verse 16

Sanskrit:

उपर्युपरि विन्यस्तनिलयेषु पृथक्पृथक् ।क्षिप्तै: कशिपुभि: कान्तं पर्यङ्कव्यजनासनै: ॥ १६ ॥

ITRANS:

upary upari vinyasta-nilayeṣu pṛthak pṛthakkṣiptaiḥ kaśipubhiḥ kāntaṁparyaṅka-vyajanāsanaiḥ

Translation:

The palace looked charming, with beds, couches, fans and seats, all separately arranged in seven stories.

Purport:

It is understood from this verse that the castle had many stories. The words upary upari vinyasta indicate that skyscrapers are not newly invented. Even in those days, millions of years ago, the idea of building many-storied houses was current. They contained not merely one or two rooms, but many different apartments, and each was completely decorated with cushions, bedsteads, sitting places and carpets.
