In that city one could clearly behold Viśvakarmā’s complete knowledge and architectural mastery. Broad avenues, squares, and market roads were laid out according to vāstu; splendid parks and wondrous gardens were filled with celestial trees and creepers. Gateway towers rose with golden pinnacles touching the sky, their upper stories fashioned of crystal. Gold-clad houses were adorned with golden pots in front, jeweled roof-peaks above, and floors inlaid with great emeralds; nearby stood treasuries, storehouses, and stables for fine horses, built of silver and brass. Each home had a watchtower and a shrine for its household deity. Filled with people of the four varṇas, the city shone especially with the palaces of Śrī Kṛṣṇa, Lord of the Yadus.
Śrīla Śrīdhara Svāmī explains that the state highways ( rathyāḥ ) were in front and the secondary roads ( vīthyaḥ ) behind, and between them were courtyards ( catvarāṇi ). Within these courtyards were surrounding walls, and within the walls stood golden residences, atop which shone crystal watchtowers crowned with golden pots. Thus the buildings were multistoried. The word vāstu indicates that the houses and buildings were constructed on ample plots of land, with plenty of room for green areas.
