The Houtmarkt has been built in the north east, and the Haarlemmerport is visible, as well as the Old Men's Almshouse, which now houses the [[Frans Hals Museum]].]]

The new citizens had a lot of expertise in linen and silk manufacture and trading, and the city's population grew from 18,000 in 1573 to around 40,000 in 1622. At one point, in 1621, over 50% of the population was Flemish-born. Haarlem's linen became notable and the city flourished. Today an impression of some of those original textile tradesmen can be had from the [[Het Menselyk Bedryf ("The Book of Trades")|Book of Trades]] document created by [[Jan Luyken]] and his son.
