This live streaming webcam shows you the Sea of Galilee from the top of the Marina Building in Tiberias where The Galilee of the Nations / The Precious Stones Experience is located.
In the background on a good day you can even see the Top of the Mount Hermon.

The Sea of Galilee (Kinneret) is Israel's largest freshwater lake. 

The most significant places in the ministry of Yeshua (Jesus of Nazareth) aren't in Jerusalem, but in the  Galilee - close to Tiberias.
