What is the meaning of the word landmarks in the recording

Привет. Меня зовут - Елена. Я каждый день стараюсь интересно провести время. Например вчера я с пользой провела день. Я прочитала очень занимательную книгу маме с домашними заботами. А еще, вчера я присматривала за своей младшей сестрой. Мы гуляли в парке, играли в снежки, строили снеговика. Это было весело! Мне надолго запомнится этот день.

Hi. My name is Elena. Every day I try to have fun. For example, yesterday I spent the day. I read a really interesting book, helped my mom with household chores. And yet, yesterday I was Babysitting for her younger sister. We were walking in the Park, playing snowballs, building a snowman. It's been fun! I will long remember this day.

На русском и перевод. Я написала примерно.

Yesterday I got up at 7 o'clock. First I did my morning exercises and then I had a shower and brushed my teeth. As for my breakfast, I ate a cereal and a cup of tea. When I was ready to go to school, I checked my personal money and went out of home. I got to school by bus. Yesterday we had 6 (7?8?) lessons, so I came back home rather early. Then, I ate my brunch and started to do my homework. I did Maths, Geography, Biology and, of course, my favourite (здесь впиши имя своей учительницы, так будет интереснее) English. After that, I spend a little tiime searching the internet. Later I had a dinner, and went to bed at 10 o'clock.
