Archaeologists are to reveal their finds from the biggest excavation in Worcester in 15 years on Thursday.
Digging in Newport Street has shown the now quiet road used to be a busy thoroughfare, leading from the medieval bridge to the heart of the city.
The work has uncovered evidence of rich merchants who lived and traded on the road in the 17th Century and before.
The excavations are part of a scheme to build new flats. The site is open to the public on Thursday afternoon.
The area derived its wealth from the cloth trade and evidence has been uncovered of the prosperous clothiers, dyers and tanners who lived and worked there.
But in the mid-17th Century, the cloth industry went into decline, and in 1781 a new bridge was built about 100m downstream.
This caused the area to deteriorate, and by the Victorian era it had become a slum characterised by pubs, squalid boarding houses and crowded tenements.
Archaeological site manager Richard Young said: "Although the new building has been designed to leave the deeper Roman and early medieval deposits intact... it is providing an exciting opportunity to examine an unusually large area of important late medieval and post-medieval remains."
Experts are soon to begin a series of deeper excavations to unearth some of the secrets of the Roman occupation of the city.
The Newport Street site is open for public tours between 1230 and 1500 BST on Thursday.
