Let $X=\mathbb R/\mathbb Z$ to be the quotient of $\mathbb R$ (with its Euclidean topology) obtained by identifying all the points of $\mathbb Z$ to a single point $\infty$.

The space can also be described as the *wedge sum of countably many circles*, also known as a *bouquet of countably many circles*.
