Leipzig Must-see

Must-see locations in Leipzig

It depends, of course, on whether you’re looking for nature, culture, history, art, music, or night life, but here are some things to check out:

  • Obviously, city center, Augustusplatz, with its new Mein Building of Leipzig University (that looks like a church, because it was built where the GDR had destroyed a centuries-old church)
  • Thomaskirche, if you want to listen to organ music, or see the final resting ground of the mortal remains of J.S. Bach
  • Moritzbastei – just behind the city skyscraper that is visible from anywhere. This is an underground bar / concert location. Literally underground, with nice round vaults
  • The area around Markt is also worth walking around
  • Clara-Zetkin-Park (esp. area around Sachsenbrücke)

echo "Please pick up the following from the store: $groceries[0]";

This isn't going to work by the way: inserting a variable's value into a string "like $x this" only works with a simple variable such as $x – for array elements you have two other options:

  1. String concatenation:

    echo "buy ".$groceries[0]." at the store";
  2. save in a variable beforehand:

It’s the one whitespace character between the </div> and the next <div!

Because of that whitespace, and because our boxes are displayed as inline-block, the browser renders an actual whitespace in the current font and size between them, and so the smaller box once again breaks to the next "line".
