As you can see, Hagåtña was one crowded city before World War II.
There was very little space between many of the houses. Around 10,000 people had to squish into that limited area in the 1930s.
One lady told me the story how her grandmother made a living being a seamstress. After she was done making a dress, she would call outside her window to the next home, asking for a woman in the neighbor's house who more or less fit the dress she had made.
She'd ask the woman, child or adult as the case may be, to try on the dress. The lady would try on the dress and model it from her own home, while grandma the seamstress examined it from her own home! Then pass the dress from home to home through the window!
Yes, that's how close.
