Tybee Island's strategic location at the mouth of the Savannah River resulted in the construction of a lighthouse in the 1770s and a defensive fortification in the 1880s. The lighthouse has been rebuilt several times but it has remained the tallest and oldest in Georgia. We climbed to the top from and from there we had a panoramic view of the island and the ocean. From that point we could also see where the Savannah River meets the ocean. The lighthouse is still in use today.
