I really enjoyed reading this post! And you were fortunate to have the streets to yourselves, seeing that it was nice and quiet.
As always, I love the architecture of these buildings. Seeing your photos, I think this is a place that needs to go on a bucket list to be visited for sure! It looks so peaceful!
Something else that struck me was the resemblance I saw when I looked at your photo of the street map of the city with the Castle of Good Hope we still have here in Cape Town, South Africa. It doesn't look the same, but at first glance, there was a resemblance I saw in the outlines.
The Castle of Good Hope was also built by the Dutch when they first arrived in South Africa. Here is a link of the layout of the Castle as seen on their website, castleofgoodhope.co.za
If you have some time, have a look and let me know if you can see that too, or is it just me?
Have a great day, @littlebee4👍!
