1. The general equation of a circle is given by  
   $$
   (x-h)^2 + (y-k)^2 = r^2
   $$
   where $$(h, k)$$ is the center and $$r$$ is the radius.

2. The given equation is  
   $$
   x^2 + (y-7)^2 = 4.
   $$
   This can be rewritten as  
   $$
   (x-0)^2 + (y-7)^2 = 4.
   $$

3. By comparing with the general equation, we find:
   - $$h = 0$$
   - $$k = 7$$
   - $$r^2 = 4$$ so $$r = 2$$.

4. Therefore, the center of the circle is $$(0, 7)$$.
The center of the circle is at (0, 7).
