Love SPARK ! Just crammed with fantastically interesting films. Thanks !

LOL the problem is not the fortress alone it was having the cannon to repel those trying to breach the walls. Along with a force to sneak out of the fortress to counter-attack the enemy.

Quite interesting. I appreciate the sketches drawn during verbal explanations at the café.

Blaye, as you mentioned, is just one of hundreds of other sites in France and I have catalogued over 1 000 similar sites in: Angola, Armenia, Austria, Bahrain, Belarus, Belgium, Bermuda, Bosnia and Herzegovina, Brazil, Bulgaria, Canada, Chile, China, Colombia, Corsica, Croatia, Cuba, Curaçao, Cyprus, Czech Republic, Denmark, Egypt, Estonia, Faroe Islands, Finland, Germany, Ghana, Greece, Grenada, Guadeloupe, Haiti, Honduras, Hungary, India, Indonesia, Iran, Ireland, Israel, Italy, Jamaica, Japan, Kaliningrad, Kazakhstan, Kenya, Latvia, Lithuania, Malaysia, Malta, Martinique, Mexico, Monaco, Montenegro, Morocco, Mozambique, Netherlands, Norway, Peru, Philippines, Poland, Portugal, Puerto Rico, Romania, Russia, São Tomé and Príncipe, Sardinia, Serbia, Sicily, Slovakia, South Africa, Spain, Sri Lanka, St Kitts & Nevis, St Lucia, Suriname, Sweden, Switzerland, Taiwan, Turkey, UK, Ukraine, USA, Vatican City, Venezuela, and Vietnam. You didn't mention the foundations of these mammoth constructions, many of which are coastal and still standing today. What about the cost? Wikipedia states that each bastion in Amsterdam cost 500 000 florins, that's over 15 000 000 coins for the city's bastions never mind the cost of the curtain walls, trench-works and associated constructions. There are hundreds of bastions in the Netherlands alone. How many millions of tonnes of earth were moved? How many millions of tonnes of stone were handled? All manually. The logistics and logic don't add-up here.

Excellent

I suppose another civil engineering aspect that wasn't mentioned about the Dutch barrier is spotting that the protection of a hundred or so kilometers of estuary coast can be achieved in just 3km by picking the right point at which to place the right protection. One of those things that are obvious in hindsight, but which straightline thinking might miss.

(2:20) - "...twelve feet wide" then, in the very next breath, "12 metres high" What the fuckity fuck? And (13:44) - Doesn't he mean "mortar", rather than "Howitzer"?
