Unter den Linden
Named for the lime trees lining its central pedestrianized strip, Unter den Linden is one of Berlin’s most famous thoroughfares, and the former hub of historic Berlin.
Many of the avenue’s once palatial buildings are being restored, and it’s a popular location for embassies, shops, outdoor cafes, museums and educational institutions.
A walk along the Unter den Linden is especially magical at night, when the trees are lit up, and during the autumn colors of fall.

The lovely avenue runs east from the Brandenburg Gate to the River Spree and Museum Island. The closest subway is Brandenburger Tor.

Unfinished Obelisk
The Unfinished Obelisk is a huge discarded granite obelisk. Three sides of the shaft, which is nearly 138 feet (42m) long, were completed except for the inscriptions. At 1,168 tonnes, the completed obelisk would have been the single heaviest piece of stone the Egyptians ever fashioned. However, a crack appeared in the rock at a late stage in the process. So it lies where the disappointed stonemasons abandoned it, still partly attached to the parent rock, with no indication of what it was intended for. It does give us an excellent insight into how these massive stone sculptures were made however.
Upon entering the quarry, steps lead down from the surrounding ramp into the pit of the obelisk where there are ancient pictographs of dolphins and ostriches or flamingos, thought to have been painted by workers at the quarry.
