Hanging Gardens of Babylonia were extremly important because it showed the pride babylonia had over many conquered nation now united as one creating a empire. Ziggurats were important because they were pyramid like buildings that were used as temples to pray and make offerings to their gods.
Accounts indicate that the garden was built by King Nebuchadnezzar, who ruled the city for 43 years starting in 605 BC (There is an alternative story that the gardens were built by the Assyrian Queen Semiramis during her five year reign starting in 810 BC). This was the height of the city's power and influence and King Nebuchadnezzar is known to have constructed an astonishing array of temples, streets, palaces and walls. According to accounts, the gardens were built to cheer up Neuchadnezzar's homesick wife, Amyitis. Amyitis, daughter of the king of the Medes, was married to Nebuchadnezzar to create an alliance between the two nations. The land she came from, though, was green, rugged and mountainous, and she found the flat, sun-baked terrain of Mesopotamia depressing. The king decided to relieve her depression by recreating her homeland through the building of an artificial mountain with rooftop gardens.
It depends on how you are defining "develop." The hanging gardens of Babylon were built in Mesopotamia, they were one of the 7 wonders of the ancient world. They probably weren't as monolithic as the pyramids, but were probably more complex architecturally than the pyramids which are essentially just artificial mountains, they're dead structures not meant to be used for any practical day to day purpose. The Hanging Gardens were something royalty would visit and use every day, they had terraces and galleries that were described as "theatre-like" by Greek chroniclers. The Hanging Gardens were destroyed by fire, something that isn't going to happen in a structure 10 people ever enter in their lifetime. Beyond that Egyptian architecture, while monolithic, wasn't technically complex. Things like gypsum mortar, concrete, the arch, domes, were not seen until Hellenistic or Persian influences brought them.

Irrigation systems have been used for several thousand years. The Hanging Gardens of Babylon were irrigated with water wheels that pumped water into the elevated gardens.

Nebuchadnezzar built the hanging gardens to please his homesick wife, Amyitis.
We Don't even know if that existed, it's only described by Herodotus as one of the seven wonders of the ancient world
Unfortunately we do not know.As far as I know nobody has found the location of the famous Hanging Gardens. All that we can surmise from the historical record was that it used to exist in the city of Babylon (now Baghdad, Iraq). But as far as I know historians and archeologists have not found its whereabouts or ruins.The Hanging Gardens were one of the seven world wonders of the ancient world. The only wonder of the ancient world still standing today is the Great Pyramid of Giza in Egypt.
the first algebra equations, the Hanging Gardens which achieved the Seven Wonders of the World list, 15 million "baked" bricks were used to build up babylon, was the most cultural cities of ancient mesopotamia, and was destroyed by the Assyrian king, Sennacherib, and rebuilt by his son, Esarhaddon.
Travel in ancient times for pleasure did exist even if the number of travels are not recorded in history. Roman have some travels recorded and the Greek also have some. The most visited places for travelers were the Colossus of Rhoda, the Egyptian Pyramids, the Hanging Gardens and the Temple of Solomon. The historians who went to the gardens did record the visit. Documents state that the gardens were built for King Nebakanezer II, king of Babylon for 43 years. Nebakanezer 's wife, Amytis, was missed her hometown when she moved to Babylon. Babylon was very flat and dry, with very little rain and therefore had very little greenery. Her hometown was very mountainous, so Nebakanezer had the gardens built for her so it would resemble where she used to live. The gardens were huge and contained many types of flowers, fruit, animals, and waterfalls, which were said to have been from places all over the world.
Technology wasn't used back then when they made it. It was around about 600B.C. So considering the era they were in, the only thing they got close to technology was their 'Chain Pump'. This got water from the Euphrates river and transported it into the gardens. This answer needs to be improved. :)
