They have one of the most well-preserved temples in all of egypt. Her temples are made of sandstone. The Hathor temple is 40,000 square meters. She had her own called "Dendera"!

Hathor's origins are conflated with the goddess Isis. As Horus (son of Ra) battles his uncle Set (sometimes known as Seth) for control of the cosmos, he becomes angry that his mother Isis isn't doing enough to help. So, he cuts off her head while she sleeps. Isis wakes up, perturbed at being decapitated, and places the first head she could find, a cow's head, on her body. This is a later story from the New Kingdom, when Isis and Hathor were often worshipped as one.

Thanks to the various myths about Hathor, there are a few ways you may see her depicted in Egyptian art. She's often shown as a woman with the head of a cow and is very occasionally shown as an entire cow (conflated with the primeval cow goddess whose milk created the Nile).

More frequently, you may see Hathor symbolized as a woman who only has the ears or horns of a cow, with the red sun disk of Horus between her horns. Her other symbol is the sistrum, a rattle-like percussion instrument which she uses to drive evil away from the world.

Egyptian mythology was obsessed with motifs of regeneration, rebirth, and cycles of existence. Humans were reborn after death, the Nile rejuvenated itself yearly, and even the Universe had to be renewed on a cyclical basis. Considering the importance of these themes, being a goddess of birth and rebirth was hardly insignificant.
