Yes. It is not known if he had a good death or not. The story is in III Kings, chapter 11:

And king Solomon loved many strange women besides the daughter of Pharao, and women of Moab, and of Ammon, and of Edom, and of Sidon, and of the Hethites: [2] Of the nations concerning which the Lord said to the children of Israel: You shall not go in unto them, neither shall any of them come in to yours: for they will most certainly turn away your heart to follow their gods. And to these was Solomon joined with a most ardent love. [3] And he had seven hundred wives as queens, and three hundred concubines: and the women turned away his heart. [4] And when he was now old, his heart was turned away by women to follow strange gods: and his heart was not perfect with the Lord his God, as was the heart of David his father. [5] But Solomon worshipped Astarthe the goddess of the Sidonians, and Moloch the idol of the ammonites.
[6] And Solomon did that which was not pleasing before the Lord, and did not fully follow the Lord, as David his father. [7] Then Solomon built a temple for Chamos the idol of Moab, on the hill that is over against Jerusalem, and for Moloch the idol of the children of Ammon. [8] And he did in this manner for all his wives that were strangers, who burnt incense, and offered sacrifice to their gods. [9] And the Lord was angry with Solomon, because his mind was turned away from the Lord the God of Israel, who had appeared to him twice, [10] And had commanded him concerning this thing, that he should not follow strange gods: but he kept not the things which the Lord commanded him.
[11] The Lord therefore said to Solomon: Because thou hast done this, and hast not kept my covenant, and my precepts, which I have commanded thee, I will divide and rend thy kingdom, and will give it to thy servant. [12] Nevertheless in thy days I will not do it, for David thy father's sake: but I will rend it out of the hand of thy son. [13] Neither will I take away the whole kingdom, but I will give one tribe to thy son for the sake of David my servant, and Jerusalem which I have chosen. [14] And the Lord raised up an adversary to Solomon, Adad the Edomite of the king's seed, in Edom.

And the rest of the words of Solomon, and all that he did, and his wisdom: behold they are all written in the book of the words of the days of Solomon. [42] And the days that Solomon reigned in Jerusalem over all Israel, were forty years. [43] And Solomon slept with his fathers, and was buried in the city of David his father, and Roboam his son reigned in his stead. 

I was doing a little research on Solomon the other day and I came across this fact.

King Solomon according to the bible had 700 wives, 300+ mistresses.

How many of you knew that? No wonder the lord brought it down to one wife only.

Anyone who has read the Bible knows that. I would hope that includes just about everyone here. Wait til you get to the part about King David.

Cassini is know in these parts for his knowledge of the Bible, which makes it all the more puzzling for me that he just discovered the fact.

I often realize things when reading the bible even now as if I had never read them. It's very strange, but keeps it interesting as I never know what I will learn next time I read it. In most cases it is just me not understanding something at the time, but sometimes it is as if I know I had never seen what I just read.

Almost everyone on CI knows this about Solomon.  Frankly, the post doesn't sound like Cassini, imo.  The chosen text/font is also odd.

Oh, I don't think there are any megalithic structures that couldn't be built today. I think we're just not familiar with the methods used in their construction.

I disagree.  I'm not talking about things on the scale of Stonehenge, but things like at Baalbek (interesting name, eh?), the largest single stone of which has been estimated to be 1,650 TONS.  Some of these stones, weighing hundreds of tons, had to have been quarried hundreds of miles from their final resting location, and others were carried up into mountains and the sides of hills.  In fact many of these cultures have stories about how the "gods" built these things for them.  That of course has been spun by the Ancient Aliens crowd, but I am a strong believer that these oral traditions are founded in truth and not just fanciful stories.  You can be darn sure that the demons were active all around the world creating false religions.

Solomon was also violating the First Commandment.  There are stories that he had this occult "ring" through which he had power over a demon (or some demons) that he used to build the temple.  I do believe that many of those ancient megalithic structures that would be impossible to build even with our modern technology were constructed with the aid of demons ... and their motivation would be clear, as the vast majority of these structures were temples for the worship of false (demonic) gods.

I believe such stories are from occult Jєωιѕн and Islamic sources. Would the Lord give Solomon instructions on how to build the Temple without providing him the means of building it? After all, the Lord did grant Solomon the gift of wisdom. Unfortunately, as time goes by, it seems that Solomon began losing it by marrying foreign women.

Note also I Kings 9:

And the Lord said to him: I have heard thy prayer and thy supplication, which thou hast made before me: I have sanctified this house, which thou hast built, to put my name there for ever, and my eyes and my heart shall be there always. [4] And if thou wilt walk before me, as thy father walked, in simplicity of heart, and in uprightness: and wilt do all that I have commanded thee, and wilt keep my ordinances and my judgments, [5] I will establish the throne of thy kingdom over Israel for ever, as I promised David thy father, saying: There shall not fail a man of thy race upon the throne of Israel. [6] But if you and your children revolting shall turn away from following me, and will not keep my commandments, and my ceremonies, which I have set before you, but will go and worship strange gods, and adore them: [7] I will take away Israel from the face of the land which I have given them; and the temple which I have sanctified to my name, I will cast out of my sight; and Israel shall be a proverb, and a byword among all people.
