Byzantine Era New Workshops
When you advance to the

Byzantine Era, your existing workshops can no longer be upgraded. This is intended, as
the Byzantine Era introduces three new workshops: the Scribe, Spice Merchant, and Carpenter.

These new workshops are the cornerstone of success in the Byzantine Era and the following eras, up to the High Middle Ages. Unlike previous workshops, each of these new workshops
requires 5 workers to operate.
Place them strategically to maximize their production output.

In the Byzantine Era, you will still need your old workshops to produce Roman Empire goods, which may be required for research, building upgrades, and Treasure Hunt negotiations. We recommend keeping one of each Roman Empire workshop until you finish the Byzantine Era. After that, they are no longer needed.
The same applies later in the

Early Gothic Era, which introduces another set of new workshops: the Jeweler, Alchemist, and Glassblower. These workshops will also require 5 workers each.
