A contemporary view of Ipswich is given by Cosmo, the future Grand Duke of Turin, who visited there in June, 1558.
I've standardized the spelling of names I know, corrected scanning errors I could figure out, and increased the number of paragraphs. Sometimes I got confused making the N.S./O.S. date conversions, so I apologize if they are wrong:
The following morning, 3/13 June 1669, having performed all his usual duties, his highness entered his carriage, and leaving Colchester, travelled over an undulating country, partly wooded and partly pasture, which continued as far as Ipswich, where he arrived in the middle of the day.
Having alighted, he took a turn round the city, which is not the least considerable in the kingdom, and then returned to the inn to dinner.
Ipswich, one of the most celebrated, and indeed the principal town in the county of Suffolk, is situated on the banks of the river Stour, which, from being subject to the influx of the tide, affords a convenient harbor to ships, and by the fulness of its stream is navigable to the sea; into which, after becoming gradually wider, it disembogues itself near the castle of Framlingham.
Its circumference is very considerable, and it was once surrounded by a wall, which however has now fallen into decay, and left the town without any defence.
It possesses many handsome buildings, as well for private residences as for public business; and, upon the whole, its appearance, with its spacious squares (piazzas) and streets, is very noble.
It is a mercantile town, and carries on commerce with other parts of the kingdom and with foreign ports, by means of vessels, which are continually coming in and clearing out; and from the encouragement there given by trade, its population amounts to upwards of 2,000 souls.
